Answer:
n ≥ 29
She needs to do more than 29 pushups on the sixth day.
Step-by-step explanation:
First, we need to use the formula for finding the average. We currently have numbers for the first 5 days.
(22+26+21+25+27+n)/6 = 25
Multiply both sides by 6.
25*6 = 150
150-27-25-21-26-22=x
x=29
Since it is an inequality, Sarah needs to do more than 29 pushups on the sixth day.
To solve this, i suggest coming up with an equation. Let “C” represent cost of production, and “x” represent number of shirts ordered.
C = 9.25x + 4.25
Since C is $87.50, plug that value in and find x.
87.5 = 9.25x + 4.25
83.25 = 9.25x
9 = x
Therefore, Diego ordered 9 shirts. I hope this helps.
I’m not gonna lie. I’m just answering so I could upload my question
B. Step 2 should’ve brought the negative sign down with the 72.
You can see that the equation went from -72 = 4x -30 to
72 = 4x - 30
