.75x-14=-8
Use inverse operations to find x
Add 14 on both sides
.75x=6
divide by .75 on both sides
x=8
Answer: 648 pull-ups
Step-by-step explanation:
Given
Max take 5.5 minutes to do 60 Pull-ups with a break in between
Similarly, it took 8 minutes for 120 pull-ups
Suppose the time taken for a single pull-up and break is x and y minutes
So, it can be written
Now, suppose max perform at this rate, and the total pull-ups are P in 30 minutes
Answer:
y = -2x + 3
Step-by-step explanation:
Hope this helps!
