x + 77 = 3(x - 6)
x + 77 = 3x - 18
x + 77 + 18 = 3x - 18 + 18
x + 95 = 3x
x + 95 - x = 3x - x
95 = 2x
x = 95/2
x = 47.5
Not much work is required to solve this I believe.... B) c= 40+170m because..... Well the fee to hook is already 40.. and you're trying to figure out the miles it was towed... the price per mile is $1.70... So you would have to multiply the money per mile and miles (m) hope this help (idk if I'm making any sense or if this is right let's hope lolll :)
C= 3b + 2d
Subtract 3b first.
C-3b = 2d
Divide by 2.
C-3b/2 = d
OR
C-3b
-------- = d Your final answer!
2
I got D for this one................
Your inequality looks like this:

To get rid of the /6, you need to multiply by 6 as the opposite operation cancels it out. So, all you need to do is multiply both sides by 6 to isolate x.
Therefore:
