Write a 2 column proof.
Given : AC = 59
Prove: x = 9
plz help i’m desperate

If you have to work it out then here's the explaining

Step-by-step explanation:

1. (2x+4) 3x10= 59. which is the given and you have to find the prove which is 9 so look at these steps carefully so you know how I got it.

2. 5x+14=59

3. 2x+4+3x+10=59 (I hope you can see that it's equal to 59 it don't change)

5x+14=59 and change it to 5x=59-14 now I got that because you have to change the sign and change what's at the end of the problem of 5x+14=59 which is 59 go to the right where 5x is at.

4. Then we subtracr 5x=59-14 which would give us.. 5x=45

5. You divide both sides by 5 *5x=45/5 which is 9.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

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!
