Matt made a 75% on his test. There were 20 questions on the test. How many questions did Matt get correct on his test?

55

Step-by-step explanation:

15

Step-by-step explanation:

1/20=5%

2/20=10%

...

if the questions he got right equals x, and each question he got right equals 5%, than x/20=75% because he got 75% right.

now to solve it.

x/20=75%

percent means divided by 100 so

x/20=75/100

x/20*20=(75/100)*20

x=0.75*20

x=15

he got 15 questions correct

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
