You take a test with 25 questions. Your grade on the test was a 80%. How many questions did you get right?
2 answers:
Answer:
20 questions
Step-by-step explanation:
1.) Use the following equation:
=
2.) For this equation,
- x is the # of test question you got right
- y is the total # of test questions
- p is the grade you got on the test
3.) Substitute
=
4.) Solve
=
=
=
5.) Cross Multiply
=
5x = 100
6.) Divide
5x = 100
x = 20
Therefore, you got 20 questions right.

slope, rate of change is.
use this formula, to find right of change we can.
input two pairs of coordinates, we must.
use 0, 1 and 5, 4, we will.
4 - 1 / 5 - 0
3 / 5
3/5, the slope is.
hmm.
convert 3/5 to decimal, we must.
multiply both sides by 2, we can.
3 * 2 = 6
5 * 2 = 10
6/10, our new fraction is.
convert to decimal, we must.
6/10 = 0.6
0.6, our slope is.
