Answer 14

ok i'm writng this down

Answer 15

ok so you have \[\frac{1}{24}x=26\]

Answer 16

ok one second i am writing all of this in order

Answer 17

now you want to isolate x, so divide both sides by 1/24. Of course this is equivalent to multiplying both sides by 24.\[x=26\times24\]\[x=624\]

Answer 19

you can use wolfram alpha to check your answers:

but of course you want to do them yourself, because there is no wolfram alpha on the exam!
