Celia uses the steps below to solve the equation -3/8(-8-16d)+2d=24



Step 1 Distribute -3/8 over the expression in parentheses.


3-16d+2d=24

Step 2 Simplify like terms.

3-14d=24


Step 3 Subtract 3 from both sides of the equation.

-14d=21

Step 4 Divide both sides of the equation by –14.

d=21/-14=-3/2=-1 1/2


Which corrects the error in the step in which Celia made the first error?

In step 1, she should have also distributed -3/8 over 2d, to get 3-16d+(-3/4d)=24.
In step 1, she should have also distributed -3/8 over –16d, to get 3+6d+2d=24. In step 3, she should have added 3 to both sides of the equation to get -14d=27.

Jessica has 48 coins, some of them are nickels and some are dimes. How many of each does she have if she has $3.25 total?

Answers

Jessica will have 17 Dimes and 31 Nickels.

Nickel = 0.05

Dime = 0.10

XNickels + YDimes = 3.25

0.05X + 0.1Y = 3.25

You could do this using trial and error.

You know the maximum amount of dimes you could have is 32. Because 32 * 0.1 = 3.20. If you had 33 dimes, you'd go over the limit.

You also know you need to have 48 coins. If you have 32 dimes and 1 nickel, you will not have 48 coins.

You can try any number below 32. I will try 16 because it's half of 32.

16 * 0.1 = 1.60

48 - 16 = 32 coins left

32 * 0.05 = 1.60

1.60 + 1.60 = 3.20

We're a nickel off, therefore we need to remove a nickel and add a dime.

17 * 0.1 = 1.70

48 - 17 = 31

31 * 0.05 = 1.55

1.70 + 1.55 = 3.25

Jessica will have 17 Dimes and 31 Nickels.

Jessica has about 31 nickels, 17 dimes which is worth $3.25

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of nickels and y represent the number of dimes.

x + y = 48   (1)

Also:

0.05x + 0.1y = 3.25   (2)

x = 31, y = 17

An airplane at cruising altitude starts descending for a landing. The function f (t) = 33,600 – 1500t describes its altitude t minutes after starting its descent. What is the airplane's altitude after 10 minutes?

Answers

ANSWER

18,600

EXPLANATION

The function that describes the altitude of the plane t minutes after starting its descent is

[tex]f(t) = 33600 - 1500t[/tex]

To find the airplane's altitude after 10 minutes, we substitute t=10 into the function.

[tex]f(10) = 33600 - 1500(10)[/tex]

[tex]f(10) = 33600 - 15000[/tex]

[tex]f(10) = 18600[/tex]

Therefore the airplane's altitude after 10 minutes is 18,600 units.

Morgan started the year with $615 in the bank and is saving $25 per week Kendall started with $975 and is spending $15 per week .when will they both have the same amount of money in the bank ?

Answers

Answer:

Step-by-step explanation:

You can represent Morgan's scenario with the expression, 25w + 615, and you can represent Kendall's scenario with the expression, 15w + 975.  To find out when they both have the same amount of money in their accounts, you set them equal to each other and solve for w:

25w + 615 = 15w + 975

25w = 15w + 360

10w = 360

w = 36

Morgan and Kendall will have the same amount of money after 36 weeks.

Final answer:

To find the week when Morgan and Kendall will have the same amount of money in the bank, we set up the equation 615 + 25x = 975 - 15x and solve for x.

Explanation:

To find the week when Morgan and Kendall will have the same amount of money in the bank, we need to set up an equation. Let x represent the number of weeks. The equation for Morgan's savings is 615 + 25x, and the equation for Kendall's savings is 975 - 15x. To find the week when they have the same amount of money, we set up the equation 615 + 25x = 975 - 15x. Solving this equation will give us the value of x, which represents the number of weeks.

615 + 25x = 975 - 15x
Combine like terms:
40x = 360
Divide both sides by 40:
x = 9

Therefore, Morgan and Kendall will have the same amount of money in the bank after 9 weeks.

Answers

No mode. There are no two or more of the same price in the given situation.

The mode is the value that appears most frequently in a set of data. In the provided data ($39.99, $44.99, $29.99, $35.99, and $31.99), each value appears only once, so this set has no mode.

The mode of a set of data is the value that appears most frequently. Taking into account the prices for a video game at five different stores, which are
$39.99, $44.99, $29.99, $35.99, and $31.99, we need to determine if any of these values appear more than once.

Since each price appears only once, there is no repeating value, therefore this set of data has no mode.

To understand the concept better, if we had a set of prices in which at least one price appears more than once, that repeating price would be considered the mode. For example, if we had the prices $29.99, $29.99, $35.99, $39.99, and $44.99, then the mode would be $29.99 because it appears twice.

= 9x^3+ 2x^2 -5x+ 4 -5x^3+ 7x -4

= (9x^3 -5x^3)+ 2x^2+ (7x -5x)+ (4-4) (combine like terms)

= 4x^3+ 2x^2+ 2x

The final answer is 2x* (2x^2+ x+ 1).

The final answer in factored form is 2x(x² + x + 1).

f(x) = 9x³ + 2x² - 5x + 4

g(x) = 5x³ - 7x + 4

To find f(x) - g(x) ,, we subtract g(x) from f(x) term by term.

Subtract the like terms from f(x) and g(x):

f(x) - g(x) = (9x³ + 2x² - 5x + 4) - (5x³ - 7x + 4) = 4x³ + 2x² + 2x

The final answer in factored form is 2x(x² + x + 1).

What is the solution of 3 sqrt x+8=-4?

Answers

Answer:

[tex]x=-72[/tex]

Step-by-step explanation:

The given equation is [tex]\sqrt[3]{x+8}=-4[/tex].

We cube both sides of this equation to obtain;

[tex](\sqrt[3]{x+8})^3=(-4)^3[/tex].

This implies that;

[tex](x+8)=-64[/tex]

We group similar terms to obtain;

[tex]x=-64-8[/tex]

We simplify the right hand side of the equation to obtain;

[tex]x=-72[/tex]

Therefore x=-72 is the solution of the given equation.

Final answer:

The equation 3 √x + 8 = -4 has no solution. The square root term, when isolated, shows a contradiction since the square root of a non-negative number multiplied by a positive constant cannot be negative.

Explanation:

The solution to the equation 3 √x + 8 = -4 involves finding the value of x for which the equation holds true. Given that √4 can be both 2 and -2, we explore the possibility of squaring both sides of an equation to solve for x. However, in this case, since the square root of a number cannot be negative and the original equation involves a square root on the left side, this hints at no solution being possible because the left side (involving the square root) will always be non-negative, and cannot equal a negative number.

Nevertheless, let's attempt to formally solve the equation. Isolating the square root term by subtracting 8 from both sides results in 3 √x = -12. At this point, we encounter a contradiction: the left side represents a non-negative value (since it's 3 times the square root of x), but the right side is negative. This confirms there are no real solutions to the equation because the square root of a non-negative number (x) cannot result in a negative value when multiplied by a positive constant (3).

five less than a number is at least 40. write and solve an inequality to find the minimum value of the number​

Answers

Answer:

45

Step-by-step explanation:

5 less than your number is at least 40. Let the number be x. So rephrasing the statement, 5 less than x is greater than or equals 40.

x-5 ≥ 40

x-5+ 5 ≥ 40+5 (adding 5 to both sides to single out the x in LHS)

∴x   ≥ 45

In other words, x is at least 45.

Therefore, the minimum value of x is 45.

Final answer:

The inequality that represents 'five less than a number is at least 40' is x - 5 ≥ 40. To solve this, we add 5 to both sides, resulting in x ≥ 45. This means the minimum value of the number is 45.

Explanation:

To express the statement five less than a number is at least 40 as an inequality, let's designate the unknown number as x. The phrase five less than a number translates to x - 5, and at least 40 means the value is 40 or greater, which we write as ≥ 40. Combining these, the inequality is x - 5 ≥ 40.

Now, we solve the inequality step by step:

Add 5 to both sides: x - 5 + 5 ≥ 40 + 5

Simplify both sides: x ≥ 45

The minimum value of x is 45; therefore, any number that is 45 or greater satisfies the inequality.

So, 8C2 = 28

The combination C(8, 2) in the given problem equals 28.

Mathematically, a combination refers to a selection of items from a larger set without regard to the order of selection. It is a way to count the number of different subsets or groups that can be formed from a given set.

In other words, a combination is a selection of r objects from a set of n distinct objects, where the order of selection is not considered. The number of combinations represented as C(n, r), represents the count of possible combinations.

It is known that C(n, r) = [tex]\frac{n!}{r!(n - r)!}[/tex],

Final answer:

The equation doesn't provide enough context to definitively solve for 'r'. Given the original equation r16 ≥ 8, r shouldn't be less than 1 if only integer values are accepted.

Explanation:

In Mathematics, the original equation provided here, 'r16 ≥ 8', seems to indicate that a value 'r' is being multiplied by 16 and the product should be greater than or equal to 8. To solve for 'r', you would normally divide both sides of the equation by 16. However, each sub-question provided 'r ≥ 2', 'r ≤ 2', 'r ≥ 128', and 'r ≤ 128', indicates different potential solutions for 'r'. Without the proper context or further information it is difficult to properly solve for 'r'. Given the original equation, if only integer values are allowed, 'r' should not be less than 1 to maintain the inequality. Further clarification on the nature of 'r' and the context of the question is highly recommended.
