Hi there’s some math apps for this
The cars travel at a 21MPH difference, so if we divide 460 by 21, we get 21.9
Answer: 21.9 hours
-8(3 - s) = 32
So you expand the brackets
-24 + 8s = 32
And then solve
+ 24
8s = 56
÷ 8
s = 7
Hope this helps!
15% of 80 is 12.
To check this, you can multiply 80 x 0.15, which gives you an answer of 12.
