Solve the equation using the distributive property and properties of equality.
-5(a+3) --55
What is the value of a?
0-14
0-8
08
0 14

-5(a + 3) = 55

Step-by-step explanation:

-5a -15 = 55

-5a = 70

70/-5 = a

70/-5 = -14

The answer is -14

it would rotate about 180 degrees.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
