Answer 1

A. x + 14.5 = 156.5
B. x – 14.5 = 156.5
C.7x + 14.5 = 156.5
D. 7x – 14.5 = 156.5

Answer 2

B i think

Answer 3

Yep :) @srw1496 is correct

Weight before minus weight lost = current weight

Answer 4

thanks

Answer 5

Shannon opens a savings account with $50. Each week after that she deposits $8 into her account. How many weeks does it take her to save $450?

Answer 6

8x+50=450

Answer 7

thanks

Answer 8

No problem(:

Answer 9

could you tell me how many weeks it takes her to save 450

Answer 10

How much extra does Shannon have to save to get from $50 to $450?

Answer 11

here are the possible answers
56.25 weeks
62.5 weeks
52 weeks
50 weeks

Answer 12

Well the equation I showed you is 8x+50=450. To solve for x (which is the number of weeks) you first have to get 8x by itself so you would subtract 50 from both sides and get 8x=400

Answer 13

Then to get x you divide everything by 8 and get x=50. It takes her 50 weeks to save $450

Answer 14

thanks

Answer 15

No problem (:

Answer 16

–6q + 5.8 = 23.8

Answer 17

Well done again :)

Answer 18

i have a lot of math trouble if you haven't noticed

Answer 19

you should post these in separate questions... then you get the "credit" for asking, plus @srw1496 can get more credit for the good help :)

Answer 20

haha I have problems with math too its fine, I'll try an help as much as I can(:

Answer 21

next semester i will be in an easier math class

Answer 22

kk

Answer 23

–6q + 5.8 = 23.8 you need to solve for q right?

Answer 24

i don't know how to get another question up other than this one

Answer 25

yes

Answer 26

q = 3
q = –3
q = –1.83
q = 4.93

Answer 27

@cheeseloverXD it's no big deal, but if you hit the "close" button near where you asked the question, you can begin a new one.

Answer 28

kk

Answer 29

well you do the same thing I showed you for the last equation. You have to get the -6q on the left side alone so you have to subtract 5.8 of both sides, can you do that?

Answer 30

btw thanks for the medal

Answer 31

haha no problem

Answer 32

how do you get a pic

Answer 33

on the profile thing

Answer 34

Did you work out that last problem?

Answer 35

no

Answer 36

go to settings and click change profile picture underneath the little pic of the owl and then click save. but back to the problem now you have -6q=18

Answer 37

–6q + 5.8 = 23.8

Step 1: subtract 5.8 from both sides
–6q + 5.8 -5.8 = 23.8 - 5.8

Step 2: simplify:
-6q = 18

Answer 38

@cheeseloverXD what's the next step?

Answer 39

now you have to get q by itself so you divide everything by -6 and what do you get?

Answer 40

18+58?

Answer 41

no, your trying to find q right?

Answer 42

yes

Answer 43

this was the only good pic I had on my comp.

Answer 44

When they did the problem they multiplied -6 by q to get 18 so to get q from 18 you have to do the opposite which is to divide both -6q and 18 by -6
