Answer:

Step-by-step explanation:

The simpler way to calculate this question is just to calculate A and B

A - 4 x (7+2) = 4 x 9 = 36

B - (4 x 7) + 2 = 28 + 2 = 30

A = 36

=> Thus, our answer is A

Answer:

A. 4 * (7+2)

Step-by-step explanation:

Let's evaluate choice A and B. Solve each expression according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

The option that equals 36 will be the correct choice.

4 * (7+2)

Solve the parentheses first. Add 7 and 2.

4 * (9)

Multiply 4 and 9.

(4*7)+2

Solve the parentheses first. Multiply 4 and 7.

(28)+2

Add 28 and 2.

When evaluated, choice A equals 36. Therefore, A is correct. When the parentheses are arranged like so: 4 * (7+2) it will be equivalent to 36.

Find the percent of increase to the nearest whole from 12 to 20

ankoles [38]

Answer:

The answer is

Step-by-step explanation:

To find the percentage increase we use the formula

<h3> $Percentage \: change = \frac{change}{original \: \: quantity} \times 100\%$ </h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3> $\frac{8}{12} \times 100 \%\\ = \frac{2}{3} \times 100\% \\ = 66.67\%$ </h3>

We have the final answer as

$67\%$ to the nearest whole number
