Step-by-step explanation:
Answer: I think it's 960.
Step-by-step explanation:
Add up all of the numbers:
(160.2+163.2+157.8+159) = 640.2
Find the average by diving 640.2 by how many numbers there are:
640.2 ÷ 4 = 160.05
Round that average^^:
160.05 >>> 160
Multiply by how many numbers there will be:
In this case, your job is to estimate how far Jose ran in 6 months, not just those 4. So instead of multiplying the average (160) by 4, you'd multiply it by 6.
160 x 6= 960
The given equation is:
5x - 4y = 12
First take y term on one side. So we can write the equation as:
5x - 12 = 4y
or
4y = 5x - 12
Next divide both sides by 4 to isolate y. The equation thus becomes:
So, third option gives the correct answer
