The first one is : (9)
By submitting --> 9
For every "X" in both of the equations its = 59
And because the question told us that the perimeter is 118 , so we multiply the 59 by 2
59x2 = 118
So , the answer is (9)
the second one is : (19)
the coverage value is 5$ , and the cost p/m is 0.15$ , so we subtract 7.85$ - 5$ we will get = 2.85$ , now by dividing 2.85$/0.15$ we will get = 19 , and that is the number of miles.
Good Luck!
