. Solve for x. Solve algebraically or use a tape diagram. 5x-6=24

3/4 x-6.5=5.5

-7.5x+3=18

Step-by-step explanation:

5x-6 = 24

5x = 30

x = 6

¾x-6.5 = 5.5

¾x = 12

x = 12×4/3 = 16

-7.5x+3 = 18

-7.5x = 15

x = 15/(-17.5) = -6/7

there are no short passages to look at

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
