Solnce55 [7]3 years ago
5 0

Answer: there were 40 questions on her math final.

Step-by-step explanation:

Let x represent the total number of questions in the math test.

Mary got 85% correct on her math test. This means that the number of questions that she got right is

85/100 × x = 0.85 × x = 0.85x

This also means that the number of questions that she missed would be

x - 0.85x = 0.15x

Therefore, if Mary missed 6 questions, it means that

0.15x = 6

Dividing both sides of the equation by 0.15, it becomes

0.15x/0.15 = 6/0.15

x = 40

Work; I made a proportion , but you can just divide 360 and 25 .
 x=14.4 miles

If Mr.Walters drives 480 miles on 32 gallons of gas , he drives 15.06 miles on 1 gallon of gas .
 x=15.06 miles
2. Mr.Walter because he drives more miles with a gallon .
Work; 15.06 miles is greater than 14.4 miles.

Hope it helps and have a wonderful day.

How do you multiply mixed numbers and fractions?
jekas [21]
First you need to convert the mixed numerals to improper fractions , for example 1 1/3 = 1/3 + 3/3 = 4/3.   Then you multiple across the numerators, the top number, and then the denominator, the bottom number.  Simplify the answer if necessary.

1 1/3 x 5/6
4/3 x 5/6 = 20/18 Divide numerator and denominator by 2
10/9  write as a mixed number 1 1/9
