(c) 5p + 7 = 12 - 3p
8p = 5
p = 5/8 = 0.625
5. (a)
7p + 2 = 5p + 8
2p = 6
p = 3
(b) 7r + 2 = 5r - 20
2r = -22
r = -11
The answer is A because there is a constant pattern
-6 - (-1 + 8)
-6 - ( 7)
= -13
If you know that the car travels 0.75 per minute and that there are 60 minutes are in a hour, you could multiply 0.75 with 60, which gives you an answer of 45.
