If you would like to know how many times does 50 go into 85, you can calculate this using the following steps:
85 / 50 = 17 / 10 = 1.7
The correct result would be 1.7.
If you use the same technique from the first question, you can do:
5x+2=3x+42
2x=40
x=20
For the rest of the questions, please use the same technique if they are vertical because I can't solve all of the questions for you sorry.

Step-by-step explanation:
To find the largest number of groups she can have, find the largest number that can divide 104 and 88 evenly.
This number is 8, since 8 divides 104 to 13 and it divides 88 to 11.
This means each group will have 13 nickels and 11 dimes.
So, the answer is 8 groups.
