Levi was correct on 80% of the questions in his math test. if levi missed a total of 10 question how many questions were on the test?

80 percent is 8/10

remainder is 2/10 so, 10 wrong = 2/10 of total

or 1/5

if it its 1/5 multiply by 5 to get total

10 * 5 = 50

50 questions

i believe that the answer is

b. y-1=-2(x-4)

hope this !

if i put something wrong your not gonna like it so rather not say nothing.
