Question

NO EXPLANATION IS NEEDED!! HELP ME WITH MY 7TH GRADE MATH!! The question is right here: Solve the problem by entering and solving the equation.


Jenny earned 82 of a possible 122 points on a test. She lost 2 points for each incorrect answer. How many incorrect answers did she have?
The equation is
122 − 2x = 82.
There are (BLANK, SOLVE THISSSSS!!!)
incorrect answers.

So just solve the equation! :)

Answer 1

Answer:

First you subtract 122 from both side to get -2x=-40. Then, you divide both sides by -2 to get x=20. So, Jenny got 20 answers incorrect.

Answer 2

Answer:

There were 20 incorrect answers

Step-by-step explanation:

Given the equation, 122 - 2x = 82:

You can solve for x algebraically:

122 - 2x = 82

122 - 2x + 2x = 82 + 2x

122 = 82 + 2x

122 - 82 = 82 - 82 + 2x

40 = 2x

40/2 = 2x/2

20 = x

Therefore, she had 20 incorrect answers worth 2 points each (in which she lost a total of 40 points).
