Tim answered all the questions on his math test but got 10 answers wrong. He received 4 points for every correct answer, and the
re was no penalty for wrong answers. His score was 76 points.
Write an equation to determine the total number of questions (q) on Tim's math test.
Find the total number of questions on his math test.
2 answers:
4x = 76
Where x is how many awnsers he got correct and 4 how many points each correct question awnsered.
Now you just have to isolate x by dividing both sides of the equation by 4
4x/4 = 76/4
x = 19
So he got 19 questions right and 10 awnsers wrong. In total there were 29 questions on his test
Answer:
q-10=76/4 29 questions
