Step-by-step explanation:
equation has infinitely many solutions has the same number on both sides of the equal sign
-3x -21 + x + 5 = -20x -16
-2x -16 = -20x -16
so either you have -18x on the left or +18x in the right
7th grade: 62/120 of the class is made up of girls; (120-62)/120 of boys.
8th grade: 58/120 of the class is made up of boys; (120-58)/120 of girls.
Looking at the info for boys only: Compare (120-62)/120 with 58/120. What do you see?
If u have to drive the car 60 miles per day, at 0.30 per mile, then u r spending
(60 x 0.30) = 18 per day on just driving.
plus the 26 per day for the rental
totals : 18 + 26 = 44 per day
44d = 350
d = 350/44
d = 7.95 rounds to 8 days
answer is 8 days
