56
Step-by-step explanation:
This is a proportion problem the answer is 400 because inches over miles = 1 over eight equals to 5 over x you cross multiply and get x = 400
5(v+2) = -2(7v-3) + 9
------------------------------------
Distribute:
5v + 10 = -14v + 6 + 9
Combine Like Terms
5v + 10 = (-14v+9v)+6
5v + 10 = -5v + 6
Subtract -5v from both sides
10v + 10 = 6
Subtract 10 from both sides
10v = -4
Reduce
5v = -2
Divide both sides by 5
v = -2/5
Simplify
v = -0.2
