Answer:
See below:
Step-by-step explanation:
Hello! We can check to see if the inequality is true by replacing r with 18 as we have been told to find them in which 18 as r makes the equation true.
So our equations to test for are:

We can input 18 as r and then we see the following are correct:
1. No, as a -21 is not greater than -6
2. Yes, as -15 is less than 6.
3. No, as 21 is not greater than 6
4. No, as -15 is not greater than 6.
Cheers!
Answer:
long pieces 126 Short pieces 21
Step-by-step explanation:
18+18+18+18+18+18+18=126
3+3+3+3+3+3+3=21

No its not, the equation your showing right now adds up to 68
Answer:
- 8
Step-by-step explanation:
Step 1:
- 50 - c = 5c - 2 Equation
Step 2:
- 50 = 6c - 2 Add c on both sides
Step 3:
- 48 = 6c Add 2 on both sides
Step 4:
- 48 ÷ 6 Divide
Answer:
c = - 8
Hope This Helps :)
