Find the ratio a: b, if it is given that 5a−3b=7b

It is 2:1 Ive tested this

Step-by-step explanation:

I did this by subtracting 5-3=2

Then (5+3)-7=1

So, 2:1 (this somehow worked on my part)

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
