This is a common factor problem.
Pencils come in a pack of 12
Erasers come in a pack of 10
First, break the number into their prime factors(the idea is that we will break the number down into its smallest multiples, which are prime numbers):
10 = 2 * 5
12 = 2 * 2 *3
So now we take the unique multiples of each number, and when we multiply them together, we will get the smallest number that both 10 and 12 can be divided into(this is what the problem is asking for)
We have (2*2*3) that comes from 12, and the only unique number that comes from the 10 is (5)
So now, we multiply:
2*2*3*5=60
However, this isn't exactly out answer. Now we have to divide our answer by the number of each this in the pack to know how many packs to buy.
60/12=5 packs of pencils
60/10= 6 packs of erasers
I hope this helps. Let me know if you have any questions!!

</span><span>Martha is doing an inventory of all the goods in her shop. For the brand Toms shoes, she should have recieved an order that would have brought the total number of Toms shoes in her store to 10 more than 5 times the number of shoes she has now. If Martha has 89 pairs of Toms in her store, how many would she have had, if she had recieved the delivery?
hope this helped :)

Answer:
(-2,9) ,(4,-3)
Step-by-step explanation:
Given the expression 2x+y=5
We are required to look for values of x and y such that when substituted into the given expression will result in the number 5
The Pairs are (-2,9) ,(4,-3)
Let us plug in the values to check
1. (-2,9)
2(-2)+9=5
-4+9=5
5=5 true
2. (4,-3)
2(4)+(-3)=5
8-3=5
5=5 true
100% = $250
divide $175 by 70 to obtain 1% then multiply by 100 for 100%
100% = $175 × = $250
