Which inequality is true when x=7? A. x + 6 ≥ 18
B. x – 6 > 18
C. 11 + x < 18
D. 11 – x ≤ 18

d

Step-by-step explanation:

when you plug in 7 where all the xs are, the only one that is true is d because 11-7 IS less than 18, but all the other ones are wrong.

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!

i agree because i see the other persons thinking is clear
