Although five of John's answers were incorrect, 90% of his answers were correct. How many questions did John answer in all?
fiasKO [112]

Answer:

John answered 50 questions.

Step-by-step explanation:

Although five of John's answers were incorrect, 90% of his answers were correct.

This means that 5 is 100 - 90% = 10% of the total number of questions, n. So

0.1n = 5

n = \frac{5}{0.1}

n = 50

John answered 50 questions.

7m+2=7n−5

Swap sides so that all variable terms are on the left hand side.

7n−5=7m+2

7n=7m+2+5

Add 2 and 5 to get 7.

7n=7m+7

Divide both sides by 7.

7

7n

=

7

7m+7

Dividing by 7 undoes the multiplication by 7.

n=

7

7m+7

Divide 7+7m by 7.

n=m+1
