Answer:
64
Step-by-step explanation:
Let x be the rate boys can eat
5x = 16
we can multiply this equation by 4 to get
20x = 64
So 20 boys can eat 64 slice of pizza
well since the formula is pi times radius squared that means it's 4 pi times 4 pi since the radius is squared so it's 16 pi
X=29 and y=10
You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.
Mean is 94.
Add all of them and then divide with add numbers and medain
