Mary jane and her sister josephine took two different tests mary jane correctly answer 20 questions and made a score of 80% on her test josephine correctly answered 14 questions and made a score of 70% girl on her test how many questions were on her test

i am having the same problem

There is 25 questions on her test

That is because for Josephine every 40% means that she got 10 questions right

40% = 10

40% = 10

20% = 10/2 or 5

I would divide 10 by 2 because 20 is half of 40 and you'll get 5

Add all the questions and you'll get

10 + 10 + 5 = 25 questions

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
