If you add the two equations, you will indeed eliminate x:
20% as a decimal is 0.2
Hope this helps!
Answer: Choice B (If you need to do questions like this in the future i recommend using the desmos graphing calculator online, inputting the equations and comparing them)
Answer:
-5 ≤m<1
Step-by-step explanation:
7 + m ≥ 2 and m + 1 < 2?
Solve the inequality on the left first
7 + m ≥ 2
Subtract 7 on each side
7-7 + m ≥ 2-7
m ≥ -5
Now solve the equation on the right
m + 1 < 2
Subtract 1 from each side
m + 1-1 < 2-1
m <1
Since this is an and
-5 ≤m<1
