Hi there! The answer is x = -1
Let's solve this equation step by step!

First collect terms.

Subtract (1/2)x from both sides.

Subtract 3 from both sides.

And finally divide by -1 3/4
Recall d = rt, distance = rate * time.
now, he has a speed rate of 56 mph for a distance of 504

so, at that speed the whole driving time is 9 hours then. Ok, he drove 2 hours today, that means he drove 7 yesterday, 9 - 2.
how many miles is it for 7 hours at 56mph? d = rt ---> d = 56 * 7
that many miles he drove yesterday.
Use these formulas to get the surface area and volume. Hopes this helps! ❤️

Because to get from 5 to 25 you need to multiply by 5 so 25 times five equals 125
