-9/4V + 4/5 = 7/8
-9/4V + 4/5 -4/5 =7/8 - 4/5
-9/4V =3/40
-9/4V÷-9/4 = 3/40 ÷ -9/4
V= -1/30
Answer:
A. $80
B. $2100
Step-by-step explanation:
Given:
80x+2100=y
Rewrite the equation
y = 80x + 2100
Where,
y = Scott's total pay (in dollars)
x = number of copies of History is Fun he sells
2100 = fixed pay
A.
Since, x = number of copies of History is Fun he sells
If x = 0
y = 80x + 2100
= 80(0) + 2100
= 0 + 2100
= 2100
y = $2100
If x = 1
y = 80x + 2100
= 80(1) + 2100
= 80 + 2100
= 2180
y = $2180
change in Scott's total pay for each copy of History is Fun he sells = $2180 - $2100
= $80
B. What is Scott's total pay if he doesn't sell any copies of History is Fun?
That is, when x = 0
y = 80x + 2100
= 80(0) + 2100
= 0 + 2100
= 2100
y = $2100
<span> To get </span>25/22<span> converted to </span>decimal, you simply divide 25 by 22. the answer to that would be <span> 1.136363636 hope this helps

To get this we divide the total miles she ran for the weeks by the no of weeks she ran.
Total miles =5.5 +7.25+10= 22.25 miles altogether.
no of weeks =3.
Average miles = 22.75 /3=7.583333≅7.58(nearest hundredth)
you can estimate 57.8 and 81 then to check you can do 57.8 divided by 81
