Are you on a test?

parthkohli · Answer

Let the number of correctly answered questions be $x$. Then the number of incorrectly answered questions is $20 -x$. The number of points you get on this test is given by $5x -2(20 - x)$.

Can you solve the inequality $5x - 2(20 - x) > 0$?

sorry i did mistake. it is incorrect, my answer.

parthkohli · Answer

$7x - 40 > 0$. 

Now what are the values for $x$?

When you get that, find the values for $20 - x$. You'd get your answer
