Currently, you have made a
75, 83, and a 78 on your tests in
math. What do you need to
make on the next test in order to
get an average of an 80?

84

Step-by-step explanation:

4 test grades with an average of 80 would have a total of 80x4=320.

75+83+78=236

320-236=84

equal to

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
