Answer:
Step-by-step explanation:
A) 4x + 6 = 2x - 12
Subtract 6 from both sides
4x + 6 - 6 = 2x - 12 -6
4x = 2x - 18
Subtract 2x form both sides
4x - 2x = 2x - 18 - 2x
2x = -18
B) 24 = 6x - 18
6x - 18 = 24
6x - 6*3 = 24
6(x - 3) = 24
Divide both sides by 6
x - 3 = 4
the answer is 600mph
because 1800miles/3 hours=600mph

Can u add the pic and I’ll answer it
a. F = ma
F/a = ma/a
m = F/a
b. F = ma
-30 = -6a
a = 5
c. F = ma
30 = 10a
a = 3
