Let X be the number of hours
Brady drives 60 mph for X number of hours, which is written as 60x.
Mary drives 45 mph for x number of hours, which is written as 45x.
The equation to solve for the number of hours is:
60x + 45x = 1365
Simplify:
105x = 1365
Divide both sides by 105:
x = 1365 / 105
x = 13 hours.
The value of y should be 8
Multiples of 12 . . . 12, 24, 36, 48, 60, 72, 84, 96
Multiples of 18 . . . 18, 36, 54, 72, 90
Smallest number that's on both lists . . . 36 .
(12 x 3) = (18 x 2) = 36 .
The integer is 9. I found it on the inter net
