Answer 3

145 + 15m?

Answer 4

Correct :)

Answer 5

then i would add the like terms?

Answer 6

Gil have a larger bank balance than phillip:
145 + 15m > 100 + 18m

Answer 7

so when i added the like terms of m, i gott 33m + 145 > 100. is that still correct so far?

Answer 8

18m - 15m = 3m

Answer 9

ohhh i thought youd have to ADD the like terms but theres a plus in front of the 15 okayyy

Answer 10

sooo what would the new continued inequality be??? im starting to get confused again..

Answer 11

yes i believe.. 3m + 145 > 100

Answer 12

How about use equal side:
3m + 100 = 145
Can you understand until this part?

Answer 13

yes

Answer 14

Can you move 100 to the RIGHT?

Answer 15

im sorry but youre just confusing me.. i know youre trying to help and all... why the heck does 100 need to be moved..

Answer 16

nevermind i think i got it.. m = 15???

Answer 17

You want to find the month m, right:

Answer 18

find the amount of months, yes.

Answer 19

I mean m < 15
So you can plug m = 10, see if if works
