Multiple and then subtract by 150 that will be your answer
Answer:
24 = questions on test
Step-by-step explanation:
Questions answered correctly = questions on test * percent answered correctly
We know that she answered 18 correctly and that 75% were answered correctly
Substitute this information into the equation
18 = questions on test *.75
Divide by .75 on each side
18/.75 = questions on test *.75/.75
24 = questions on test
Area of rectangle = Length*width
A = 28 so 28 = 4 * height
height = 28/4 = 7
