5 0

Answer:

d) x = 2

Step-by-step explanation:

3(x - 6) + 3 = -9

<em>open the parenthesis</em>

3x - 18 + 3 = -9

3x - 15 = -9

<em>add 15 to both sides of the equation</em>

3x - 15 + 15 = - 9 + 15

3x = -9 + 15

3x = 6

<em>divide both sides by 3</em>

3x/3 = 6/3

x = 6/3

x = 2

If I can paint 96 sq ft in 15 minutes how long does it take to paint 1 sq ft
White raven [17]

It takes 0.15625 minutes to paint 1 square feet

<em><u>Solution:</u></em>

Given that, I can paint 96 sq ft in 15 minutes

To find: Time taken to paint 1 square feet

From given,

96 square feet is painted in 15 minutes

Let "x" be the time taken to paint 1 square feet

Then, we can say,

96 square feet = 15 minutes

1 square feet = x minutes

This forms a proportion and we can solve the sum by cross multiplying

96 \times x = 15 \times 1\\\\x = \frac{15}{96}\\\\x = 0.15625

Thus it takes 0.15625 minutes to paint 1 square feet
