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.

5 divided into 290 show work
Archy [21]
How many times does 5 go into 29? It can go into it 5 times which equals 25. Now what's 29 - 25? 4 is the answer then you see how many times can 5 go into 4, well it can't so then you bring the number 0 to make it 40. Now how many times can 5 go into 40? It can go into 40 eight times since 8x5=40 so the answer is 58

One ticket to a ride of the merry-go-round ​at the Sunday Fair costs $2.
sammy [17]

Considering the definition of an inequality, the maximum number of tickets that they can buy is 10.

<h3>Definition of inequality</h3>

An inequality is the existing inequality between two algebraic expressions, connected through the signs:

  • greater than >.
  • less than <.
  • less than or equal to ≤.
  • greater than or equal to ≥.

An inequality contains one or more unknown values ​​called unknowns, in addition to certain known data.

Solving an inequality consists of finding all the values ​​of the unknown for which the inequality relation holds.

<h3>Maximum number of tickets that they can buy</h3>

In this case, you know that

  • One ticket to a ride of the merry-go-round ​at the Sunday Fair costs $2.
  • Jenny and her friends have $36 with them.
  • After buying tickets to the merry-go-round, they want to be left with no less than $15.

So, they want to spend on the purchase of tickets for the merry-go-round a value less than or equal to $36 - $15= $21.

Being "x" the maximum number of tickets that they can buy, the inequality that expresses the previous relationship is

2x≤ 21

Solving:

x≤ 21÷2

<u><em>x≤ 10.5</em></u>

Then, the maximum number of tickets that they can buy is 10.
