The answer should be 42.
Since there are 60 questions in the test and she managed to answer 70% of the questions correctly, that means that she answered 70% out of 60 questions correctly.
So you need to calculate how much 70% out of 60 is. Since % is always measured on a base from 0 (%) to 100(%), then 70% is equal to the fraction 70/100, simplified to 7/10. To know how much 7/10 out of 60 is,you just multiplie them and your answer will be 42.
I hope this helps you forward.

Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
4a) x / 12 = 5
multiply both sides of equality by 12
x = 60
4b) Dan charges $12 per hour, this doesn't change so it's the constant of proportionality.
4c) S = 12h
If you substitute the h with the number of hours worked multiply with the constant of proportionality 12 you'll get the amount charge S.
5) Equation for a slope is (y₂ - y₁) / (x₂ - x₁):
(2 - 0) / (6 - 1)
= 2/5
