Step-by-step explanation:
3x - 9 +2x + 9 = 2x - 2
5x = 2x - 2
5x - 2x = - 2
3x = - 2
x= - 2/ 3
Answer:
The ratio of red to green crayons is 18 to 24 which can be reduced to 3 to 4.
Step-by-step explanation:
Part A : y=$0.75m+$4.50
Part B : $8.25
(m + 12) / 9m = 5 / 9
cross multiply
(5)(9m) = 9(m + 12)
45m = 9m + 108
45m - 9m = 108
36m = 108
m = 108/36
m = 3 <==
The answer is B because its going 90m/s and and in 2 seconds its traveled 180 meters which if you add to 60 gives you 240
