Write a proportion to find how many points x a student needs to score on a test worth 50 points to get a test score of 40%.

20 pts

Step-by-step explanation:

50 points corresponds to a 100% grade.  How many points (x) correspond to a 40% grade?

     x            40%

=

50 pts       100%

Then 100x = 2000, and so x = 20.

A score of 20 points would correspond with a test score of 40%.  

i need the options

step-by-step explanation:

1 x=22.52

2: 65/39=604+39x

26x=604

x=604/26

×=23.23
