Answer:
20 ≤ x ≤ 70
Step-by-step explanation:
Given that:
30 ≤ x + 10 ≤ 80
By solving the left half inequality first:
30 ≤ x + 10
Subtracting 10 from both sides:
30 - 10 ≤ x + 10 -10
20 ≤ x
Now solving inequality of right half:
x + 10 ≤ 80
x + 10 -10 ≤ 80 - 10
x ≤ 70
So after simplification we get:
I hope it will help you!
250 and 2 because i think 250 multiply by 2 is 500
I think if I done it right 15 I hope it helps
The stuff that is yellow is the answer!
