A student missed 30 problems on a chemistry test and received a grade of 47%. If all the problems were of equal value, how many problems were on the test?

-50/3 is the final answer! : )

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!

x = -5
