Answer:

x = 9

Step-by-step explanation:

-59 = 3x - 2(7x - 20)

-59 = 3x - 14x + 40 ;(distributive property)

-59 = -11x + 40

-59 - 40 = -11x

-99 = -11x

9 = x

Hello from MrBillDoesMath!

Answer: x = +9

Discussion:

-59 = 3x -2 (7x -20) or

-59 = 3x - (2*7)x - 2 ( -20) or

-59 = 3x -14x + 40 or

-59 = -11x + 40. Subtract 40 from each side

-59 - 40 = -11x or

-99 = -11x

or x = + 9

Thank you,

MrB

Question:

The shaded portion of the bar model in Part A shows 3/8. What percent is equivalent to 3/8? Enter the correct answer in the box.

Answer:

The equivalent is 37.5%

Step-by-step explanation:

Given

$\frac{3}{8}$

Required

The equivalent

<em>The model is not shown, but the question can still be solved.</em>

We have:

$\frac{3}{8}$

Multiply by 100%

$\frac{3}{8} = \frac{3}{8} * 100\%$

$\frac{3}{8} = 0.375 * 100\%$

$\frac{3}{8} = 37.5\%$
