see explanation
Step-by-step explanation:
the result 0 = 0
means the equation has an infinite number of solutions
divide $4.50 by 5 .......
3x + 9 = 90
3x = 90 - 9 = 81
x = 81/3 = 27
x = 27
The parking lot is 14 yards long by 7 yards wide.
A = W x L The formula is ....
L = W + 7 The problem tells us that ...
A = W (W + 7)
A = w^2 + 7w
98 = w^2 + 7x
... continue from there
4 I think because you subtract all since it's 60 min
