Answer 1

For number 13.) you would have to get n by itself. How would you?

Answer 2

would i first add the mixed number frations and then add n+5?

Answer 3

Not exactly, you wouldn't add them. In order to get n by itself, you would have to move 5 3/7 to the other side of the equal sign by way of subtraction

Answer 4

and that would make it 1 3/7

Answer 5

Exactly! Since you subtracted the whole numbers and then the mixed numbers

Answer 6

ok

Answer 7

Ill do one more with you, but then I have to go somewhere, sorry

Which one seems the most confusing on your list?

Answer 8

thats ok and number 15

Answer 9

So we have two different denominators, one of them is 5 and one of them is 10. What we need to do is first, make them both the same. In most cases you see if the smaller number can be multiplied by a whole number to get the larger one

Can 5 be multiplied by a whole number to get 10? If so 5 times what is 10?

Answer 10

5*2

Answer 11

Correct!

Now since the fraction was in terms of 5, we have to do the same to numerator

So 5* 2 was 10, which makes 2 (The numerator) * 2 = 4, right?

That gives us x+3(4/10) = 4(7/10)

Now we wanna do what we did in the last step and move the 3(4/10) to the other side by way of subtraction

Answer 12

1 3/10 ?

Answer 13

Yes, good work!

Answer 14

ok thank you for the help

Answer 15

Anytime!
