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>

Answer:
The number of boys who play tennis is 36.
Step-by-step explanation:
Let the number of boys who play tennis is x.
number of boys who play cricket = y
x = 3 y..... (1)
12 boys plays both cricket and tennis.
According to the question,
x - 12 = y + 1 2
3 y - 12 = y + 12
2 y = 24
y = 12
So, the number of boys who plays tennis is x = 3 x 12 = 36.
Answer:
The domain is all real numbers. The range is {y|y ≤ 16}
Step-by-step explanation:
we have

This is a the equation of a vertical parabola open downward
The vertex is a maximum
The vertex is the point (-1,16)
see the attached figure
therefore
The domain of the function is all real numbers ----> interval (-∞,∞)
Te range of the function is

All real numbers less than or equal to 16 ----> interval (-∞,16]
Answer:
no solution
Step-by-step explanation:
4( − 11) = 15 − 4
-44 = 11
Since this iS FALSE, it means that the equation given has no solution
