Hey there!
It is said we need to find the unit rate.
What we can do is apply Unitary Method.
3 minutes = 42 push ups
1 minute = 
<u>So, 12 push ups per minute is the unit rate.</u>
In 5 minutes, he will do 12×5 = <u>60 push ups!</u>

0.75 or 3/4 that’s your answer as a decimal and fraction :)
−3(n+3)−10(8n+9)
(−3)(n)+(−3)(3)+(−10)(8n)+(−10)(9)
=−3n+−9+−80n+−90
=−3n+−9+−80n+−90
=(−3n+−80n)+(−9+−90)
=−83n+−99 <- ANSWER
