Which equation, when solved, results in a different value of x than the other three?
kicyunya [14]
I would have to say -7(1/8)x-4/3=20.


The first and the second one both result in
-23 5/7

The last one results in -24 8/21

but the third one is -22 3/8.

So your answer is either the third of the last one. I assumed the third because, it is lower than all others and the first two are closer to 24 than they are to 22. It’s your choice on how to judge it.

Clayton and Timothy took different sections of Introduction to Economics. Each section had a different final exam. Timothy score
Andrews [41]

Answer: Fourth option is correct.

Step-by-step explanation:

Since we have given that

Timothy scored 83 out of 100.

His percentile rank in his class = 72

Clayton scored 85 out of 100.

His percentile rank in his class = 70.

Since Clayton's percentile rank is lower than Timothy's rank.

So, Timothy performed better with respect to the rest of the students in the class.

Hence, Timothy as his percentile score is higher.

Therefore, Fourth option is correct.
