➷ Find the area per tile first:
area = length x width
Substitute the values in:
area = 3 1/8 x 2 3/4
area = 275/32
Multiply this by 9:
275/32 x 9 = 77.34375 in^2
You can round the value accordingly.

Answer:
r = -39
Step-by-step explanation:
So we are trying to solve the equation for r.
-6(2r + 8) = -10(r - 3)
Divide both sides by -2. (This will make distributing much easier.)
3(2r + 8) = 5(r - 3)
Distribute the 3 on the left side and the 5 on the right side,
6r + 24 = 5r - 15
Subtract 24 from both sides.
6r = 5r - 39
Subtract 5r from both sides.
r = -39
So now we have solve the equation.
I hope you find my answer and explanation to be helpful. Happy studying. :)
3a + a - 15 = 225 . your substituting b(a-15) into the first equation. <span />
The answer is letter c because she makes $240.
