Solve the proportions.

12. 2/3 = n/12 13. 33/t = 3/28 14. k/6 = 15/18

15. x/5 = 3/8

12. n = 8

13. t = 308

14. k = 5

Step-by-step explanation:

12. 2/3 = n/12

Multiply by 4 because 3×4 = 12

So, n = 8

13. 33/t = 3/28

Multiply by 11 because 3×11 = 33

So, t = 308

14. k/6 = 15/18

Multiply by 3 because 6×3 = 18

So, 3k = 15. k = 5

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!
