<span>To find the z score, we need to use the following formula: (raw score - Mean)/ standard deviation. We know that the raw score is 80, the standard deviation is 10.27, and the mean is 70.27, so plugging in those values gives us: (80 - 70.27)/10.27 = 0.9474</span>

The equation 9 y minus 6 x = 36 is written in standard form. What is the first step when writing an equivalent equation which so
enot [183]

Answer:

D. Subtract 9y from both sides of the equation.

Step-by-step explanation:

A. Divide both sides of the equation by 36.

B. Multiply both sides of the equation by 6.

C. Add 9y to both sides of the equation.

D. Subtract 9y from both sides of the equation.

Given:

9y - 6x = 36

To solve for x

Step 1: subtract 9y from both sides

9y - 6x - 9y = 36 - 9y

- 6x = 36 - 9y

Step 2: Divide both sides by -6

- 6x / -6 = (36 - 9y) / - 6

x = (36 - 9y) / - 6

The answer is

x = (36 - 9y) / - 6
