Answer:

78%

Step-by-step explanation:

Ok to solve this we can write this as

80 = [tex]\frac{73+82+85+83+x}{5}[/tex]

We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%

Your grade is the average of all of your scores hence the divided by 5

We next multiply both sides of the equation by 5 to get

400 = 72+82+85+83+x

400=  322+ x

78 = x

He must get a 78% minimum on his next test to get 80%

Hope that helps!

pages per minute, which can be modeled with the equation
p
=
33
m
where
p
represents the number of pages and
m
represents the number of minutes passed. The rate at which the second printer functions is shown in the table.



Which printer should Roger choose, and how many more pages a minute will he be able to print?


Printer A;
5
more pages per minute
Printer A; 5 more pages per minute

Printer B;
2
more pages per minute
Printer B; 2 more pages per minute

Printer B;
5
more pages per minute
Printer B; 5 more pages per minute
