Acopy machine makes 165 copies in three minutes and 45 seconds how many copies of them make per minute

So we just divide 165 by 3.75 to get 44 copies per minute.

Hi!

So I would do this problem by dividing 165 copies by 3 minutes and 45 seconds; that's finding how many 3 minutes and 45 seconds go into 165, and results in how many copies are made in a minute.

Since 3 minutes and 45 seconds is in reality, 3 3/4 minutes, as there are 60 seconds in a minute, I would divide by 3 3/4, or 3.75.

165 / 3.75 = 44

So therefore, a copy machine makes 44 copies per minute.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
