Jade took a math test with 20 questions is worth an equal number of points. the test is worth 100 points in total. write an equation that can be used to calculate jade's score based on the number of questions she got right on the test.

Step-by-step explanation:

Because all the questions have the same point, we can find the weight (value) of each question dividing the total points by the total number of answers questions:

Now with the weight of each question the only thing we should to do is to multiply it by the number of the questions she got right:

Let check if our equation works, if Jade got all the answers right, we expect she got a 100 score. Let verify on the equation

, that's what we expected

If she got 10 right answers, we expect 50 score and if she got 0 right answers, we expect 0 score, let check again:

Again, we obtain the expected scores, so we can conclude our equation works.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

answer: x=60
