What is the answer to
6(3x-5)-7x=25

Answer:

7ft

Step-by-step explanation:

p=paul's height

s=steve's height

t=theresa's height

p=s

1 and 1/2=3/2

1 and 1/3=4/3

p=-16+(3/2)t

s=-6+(4/3)t

p=s so

-16+(3/2)t=-6+(4/3)t

add 6 to both sides

-10+(3/2)t=(4/3)t

times both sides by 6 to clear fractions

-60+9t=8t

minus 9t both sides

-60=-t

times -1

60=t

t=60

theresa is 60 inches or 5ft

steve and paul are 84 inches or 7ft (wow!)

Answer:

Step-by-step explanation:

8(4x + 8) = 160.....distribute the 8 thru the parenthesis

8(4x) + 8(8) = 160

32x + 64 = 160....subtract 64 from both sides

32x + 64- 64 = 160 - 64

32x = 96

x = 96/32

Answer:

LxWxH

Step-by-step explanation:

Volume can be calculated by using the formula: (length) x (width) x (height)

In this particular question, you are given the length as 13cm, the width as 8cm, and the height of 22cm.

To obtain the volume, you should plug these numbers into the formula (length) x (width) x (height)

When plugged in, the equation should look like this: (13cm) x (8cm) x (22cm).

When 13 x 8 x 22 =2288cm

Since you are calculating the volume, the answer will be given in centimeters cubed, so your final answer will be 2,288cm^3

Hope this explanation helps :)

Answer:

I think the answer is 2288 cm

In order to find volume of a rectangular prism you have to do l x w x h (length times width times height)

13 x 8 = 104

104 x 22 = 2288

I hope its right sorry if nott:(

Step-by-step explanation:

=============================================

Work Shown:

f(x) = 6x + b

f(5) = 6(5) + b .... replace every x with 5

f(5) = 30 + b

1 = 30 + b ..... replace f(5) with 1, since f(5) = 1 was given.

1-30 = 30 + b - 30 .... subtract 30 from both sides

-29 = b

b = -29

-----------

The function f(x) = 6x+b turns into f(x) = 6x+(-29) which is equivalent to f(x) = 6x-29

Plugging in x = 5 leads to

f(x) = 6x-29

f(5) = 6(5) - 29

f(5) = 30 - 29

f(5) = 1

So we have confirmed the answer.

Answer:

Step-by-step explanation:

f(5) = 1

6*5 + b = 1

30 + b = 1

b = 1 - 30 = -29

b = -29

Solved given expression for x using the change of base formula log base b of y equals log y over log b is 4.459

Answer: Option D

Step-by-step explanation:

Given Expression:

             [tex]2^{x-1}=11[/tex]

To solve this, first convert the exponential form into log form

If  [tex]a^{x}=b[/tex] then [tex]\log _{a}(b)=x[/tex]

So, when comparing the given expression with above,  a = 2, x = x – 1 and b = 11 .

            [tex]2^{x-1}=11[/tex] become [tex]\log _{2}(11)=x-1[/tex]

Now, apply change of base formula to remove base 3

             [tex]\log _{a}(y)=\frac{\log y}{\log a}[/tex]

Hence,

            [tex]\log _{2}(11)=\frac{\log 11}{\log 2}[/tex]

Substitute [tex]\log _{2}(11)=x-1[/tex] in above expression, we get

           [tex]\frac{\log 11}{\log 2}=x-1[/tex]

           [tex]\frac{1.0414}{0.301}=x-1[/tex]

           x – 1 = 3.459

          x = 3.459 + 1 = 4.459

Final answer:

To solve the equation 2^(x - 1) = 11 for x, one can use the change of base formula by taking the logarithm of both sides, rewriting the equation using logarithm properties, isolating x, and then simply calculating using a calculator, which results in x ≈ 1.289.

Explanation:

To solve 2(x − 1) = 11 for x using the change of base formula, take the logarithm of both sides of the equation and use the formula logb(y) = log(y) / log(b), where y is the number we want to take the logarithm of and b is the base of the logarithm.

Let's start the process:

Now, calculate the right side of the equation using a calculator:

Hence, the correct answer is B) 1.289.

Option C. 832 miles

Step-by-step explanation:

Ashley travels between 204 and 272 miles in every 4 hours.

That means she travels between 51 [tex](\frac{204}{4}miles)[/tex] and 68 ([tex]\frac{272}{4}miles)[/tex] per hour.

Therefore, in 12 hours she will travel between 612 (51×12 miles) miles and 816 (68×12 miles).

Since she has already traveled 118 miles before 12 hours then the distance traveled by her till now will be between 730 (612+118 miles) and 934 (816+118 miles).

From the given options, Option C. 832 miles is the reasonable measure of Ashley's distance from the starting point.

4.75 lbs of water and 0.25 lbs of sugar is needed to make 5% of syrup.

Solution:

Let us assume that x is the required pounds sugar to make 5% syrup

[tex]\Rightarrow\frac{x}{\text{total quantity}}=5\%[/tex]

which is [tex]\frac{x}{5}=5\%[/tex]

On solving we get,

[tex]\Rightarrow\frac{x}{5} =0.05 [5\%=\frac{5}{100}][/tex]

[tex]\Rightarrow x = 5\times0.05\rightarrow x=0.25[/tex]

If the required sugar to make 5% syrup is 0.25 lbs then the remaining quantity in the total sugar syrup would be water. That is,

[tex]5 \text{ lbs }-0.25 \text{ lbs }=4.75 \text{ lbs }[/tex]

So, the required amount is 0.25 lbs of sugar and 4.75 lbs of water.

Answer:

4.75 lbs of water and 0.25 lbs of sugar is needed to make 5% of syrup.

Answer:

Cost of one glove pair is $ 8.50 and the cost of one hat is $6.50

Step-by-step explanation:

Let g represents the cost of one gloves pair

h represents the cost of one hat

Then

Cody brought two pairs of gloves and four hats for $43.00

This can be written as

2g + 4h = 43-------------------(1)

Tori bought two pairs of gloves and two hats for 30.00

This can be written as

2g + 2h = 30------------------(2)

Subtracting (2) from (1)

2g + 4h = 43

2g + 2h = 30

(-)

--------------------------

0g + 2h = 13

------------------------------------

2h =13

h = 13 / 2

h = 6.5---------------------(3)

Substituting (3) in (2)

2g + 2(6.5) = 30

2g + 13 = 30

2g = 17

g = 17 / 2

g = 8.5

So one hat is $6.50 and one pair of gloves is $8.50.

Step-by-step explanation:

The question involves solving simultaneous linear equations, a high school level topic in mathematics. Methods like substitution or elimination can be used to find the values of the variables.

The student's question involves solving simultaneous linear equations, which is a topic in mathematics. To solve the given system of equations, one can use methods such as substitution, elimination, or matrix operations like determinants. The elimination method can be particularly efficient. For example, you can multiply the first equation by a number that will allow the x or y terms to cancel out when added or subtracted from the second equation. After simplifying, you're left with one equation in one unknown, which can be easily solved. Then, back-substitute the known value into one of the original equations to solve for the other variable.

Given the equations 3x + 7y = -5 and 8x + 9y = 6, we may choose to multiply the first equation by 3 and the second by 7 (to eliminate the x terms) or to multiply the first equation by 8 and the second by 3 (to eliminate the y terms). Once one variable is eliminated, we solve for the other and use it to find the value of the remaining variable.

We have the equation of a line in a standard form.

Convert to the slope-intercept form:

[tex]2x-y=-1[/tex]         add y to both sides

[tex]2x-y+y=-1+y[/tex]

[tex]2x=-1+y[/tex]            add 1 to both sides

[tex]2x+1=y\to y=2x+1[/tex]

The slope intercept form of the given equation is y = 2x+1

An equation is a mathematical statement that shows that two mathematical expressions are equal.

For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

(ii) 3x + 5 = 15

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Given that, an equation of a line, 2x-y = -1, we need to convert this into slope intercept form,

The standard form of the equation of a line in slope intercept form, is given by :

y = mx+c

Where, m = slope of the line, c is the y-intercept,

So, the given equation is 2x-y = -1,

Add y both the side,

2x-y+y = -1+y

2x = -1+y

Add 1 in both sides,

2x+1 = y+1-1

y = 2x+1

Hence, the slope intercept form of the given equation is y = 2x+1
