Bernard solved the equation 5x+(-4)=6x+4 using algebra tiles. Which explains why Bernard added 5 negative x-tiles to both sides in the first step of the solution?
A) He wanted to create zero pairs on the left side of the equation to get a positive coefficient of x on the right side.
B) He wanted to combine more negative tiles with the 4 negative tiles on the left side of the equation.
C) He wanted to remove the larger coefficient on the left side of the equation.
D) He wanted to have 10 x-tiles on the left side of the equation.
Answers
You could add 4 to both sides.
You could subtract 4 from both sides.
You could subtract 5x from both sides.
You could subtract 6x from both sides.
Any of these work. In Bernard's case, he added 5 negative x tiles, meaning he subtracted. C and D already make no sense, but allow me to further explain. By him subtracting 5x from both sides, the equation turns into:
-4 = x + 4
By this point, he can just subtract 4 from both sides to find the value of x. But the question asks for why he did the first step. Therefore, it would be A.

Please Help!!! "What is the area of trapezoid ABCD? Enter your answer as a decimal or whole number in the box. Do not round at any steps."
Answers
AB = (-3,2) and (1,5)
BC = (1,5) and (7,-3)
CD = (7, -3) and (0, -2)
AD or DA = (0,-2) and (-3,2)
Now, just use the distance formula for each line. Doing so gives us:
AB = 5
BC = 10
CD = 7.071107...
DA or AD = 5
The height is AB, the first base is BC and the second base is CD. We can plug the values for these sides into the trapezoid area formula, which is A = base 1 + base 2 all over 2 times the height. Doing so gives us 37.5 units². Therefore, the answer to your query is 37.5 units². Hope this helps and have a nice day!

Which phrase accurately describes a distribution that's bell shaped but not symmetric
Answers
Answer:
The distribution is skewed (either to the left or to the right).
Step-by-step explanation:
Skewness is the measure of how symmetric the distribution of the data is around its mean. It can be skewed either to the left or to the right (meaning that one of the "tails" of the distribution is longer than the other). This means that the mass your data set's observations tends to accumulate more around one extreme of the distribution than around the other.
A strictly symmetric, normal distribution would have a skewness measure of 0.

Fred has a savings account balance of $1728.57. The interest-rate on the account is 3.4% compounded daily. If he opened the account nine years ago, what was the value of his initial deposit?
Answers
A=p (1+r/k)^kt
A current balance 1728.57
P initial deposit ?
R interest rate 0.034
K compounded daily 365
T time 9 years
Solve the formula for p
P=A÷(1+r/k)^kt
P=1,728.57÷(1+0.034÷365)^(365×9)
p=1,272.91
Hope it helps!
Fred's initial deposit, considering a 3.4% interest rate compounded daily over nine years, was approximately $1258.16.
To find Fred's initial deposit, we need to use the formula for compound interest:
A = P(1 + r/n)ⁿᵗ, where:
Here, we know:
A = $1728.57r = 0.034 (3.4% interest rate)n = 365 (compounded daily)t = 9 yearsWe need to find P. Rearrange the formula to solve for P:
P = A / (1 + r/n)ⁿᵗ
Substitute the known values:
P = 1728.57 / (1 + 0.034/365)³⁶⁵×⁹
First, calculate the daily interest rate
0.034 / 365 = 0.00009315
Next, calculate the exponent:
(365 × 9) = 3285
Now, compute (1 + daily interest rate) raised to the power of 3285:
(1 + 0.00009315)³²⁸⁵ = 1.37423
Finally, divide the final amount by this value:
P = 1728.57 / 1.37423 = 1258.16.

henry is following the recipe card to make a cake. he had 95 cups of flour. how many cakes can henry make?
flour needed for each cake
2 2/9 cups of batter
1/2 cup for topping
Answers
total flour needed = flour need for batter + flour needed for topping
Substituting,
total flour needed = 2 2/9 cups + 1/2 cup = 49/18 cups
Then, we divide the total amount of flour by the answer obtained above to determine the number of cakes that can be made.
number of cakes = total amount of flour / total flour needed per cake
number of cakes = 95 cups / (49/18) = 34.89 cakes
Hence, the number of cakes that can be produced is only 34.
Answer:
the number of cakes that can be produced is only 34.
Step-by-step explanation:
total flour needed = flour need for batter + flour needed for topping
,
total flour needed = 2 2/9 cups + 1/2 cup = 49/18 cups
after, we divide the total amount of flour by the answer obtained above to determine the number of cakes that can be made.
number of cakes is the total amount of flour needed per cake
number of cakes is 95 cups / (49/18) = 34.89 cakes
the number of cakes that can be produced is only 34.

A)2/15
B)4/15
C)1/30
D)1/4
Answers
Answer: A is the right answer .Probability of the book chosen is a biography is [tex]\frac{2}{15}[/tex].
Step-by-step explanation:
According to the given graph or pie chart
The number of biography books=4
Total books= Romance books+ Science fiction books+ Biography books+Adventure books =2+14+4+10=30
Let B be the event of choosing a biography book then
Probability of the book chosen is a biography P(B)=[tex]=\frac{biography\ books}{total\ books}=\frac{4}{30}=\frac{2}{15}[/tex]
Therefore, Probability of the book chosen is a biography is [tex]\frac{2}{15}[/tex].
From the graph, it is found that there is a [tex]\mathbf{\frac{2}{15}}[/tex] probability that the book chosen is a biography, and the correct option is given by option A.

there are 45 cans of mixed nuts if each can has 338 nuts what is the total number of nuts,n, in all of the cans
Answers
The total number of nuts in all the cans is found by multiplying the number of cans (45) by the number of nuts in each can (338). Hence, the total number of nuts, n, in all of the cans is 15210.
Explanation:This problem is related to simple multiplication. Here, you have 45 cans of nuts and each can contains 338 nuts. So if you want to find the total number of nuts in all the cans, you need to multiply 45 (total number of cans) by 338 (number of nuts in each can).
The multiplication is as follows:
45 * 338 = 15210
So, the total number of nuts, n, in all of the cans is 15210.

A sofa is on sale for 357 which is 32 percent less than the original price how much is the original price
Answers
x - 357 / x = 32 / 100
(cross multiply)
100(x - 357) = 32x
100x - 35700 = 32x
(subtract 100x from both sides)
-35700 = -68x
525 = x
so the sofa was originally $525
The sofa's original price is calculated by using the formula: original price = sale price/percentage in decimal format. In this case, the percentage is 68%, and hence the original price would be 357 / 0.68 which is equal to $525.
Explanation:This is a percentage problem. If the sale price of $357 represents 68% of the original price (because 100% - 32% is 68%), we can find the original price of the sofa using the formula: original price = sale price/percentage in decimal format.
Therefore, the original price would be 357 / 0.68 = $525

Step-by-step explanation:
By definition the deferment period is a time during which a borrower does not have to pay interest or repay the principal on a loan.
In this case the balance should be the initial value $17,190, but Felicia made 12 payments of $589 each one.
So, $589 x 12 = $ 7,068.
$17,190- $ 7,068 = $10,122

Problem: Find the value of $x$ that maximizes $$f(x) = \log (-20x + 12\sqrt{x}).$$ If there is no maximum value, write "NONE".
Answers
Answer:
The value of x is 0.09
Step-by-step explanation:
Here, the given function is,
[tex]f(x)=\log(-20x+12\sqrt{x})[/tex]
Differentiating with respect to x,
[tex]f'(x)=\frac{1}{-20x+12\sqrt{x}}(-20+\frac{12}{2\sqrt{x}})[/tex]
[tex]=\frac{-20+\frac{6}{\sqrt{x}}}{-20x+12\sqrt{x}}[/tex]
[tex]=\frac{-10+\frac{3}{\sqrt{x}}}{-10x+6\sqrt{x}}[/tex]
[tex]=\frac{-10\sqrt{x}+3}{2\sqrt{x}(-5x+3\sqrt{x})}[/tex]
Again differentiating with respect to x,
[tex]f''(x)=-\frac{(-10\sqrt{3}+3)(-15x+3\sqrt{3})}{4x\sqrt{x}(-5x+3\sqrt{x})}[/tex]
For maxima or minima,
[tex]f'(x) = 0[/tex]
[tex]\implies \frac{-10\sqrt{3}+3}{2\sqrt{x}(-5x+3\sqrt{3})}=0[/tex]
[tex]\implies x \approx 0.09[/tex]
At x = 0.09,
f''(x) = negative,
Hence, for x = 0.09, f(x) is maximum.
