3x+9 is the answer x is the quantity and its tripled and more than 9
Answer:
72 : n = 18. n x 18 = 72
n : 18 = 72. 72 x 18 = n
72 : 18 = n
Step-by-step explanation:
You start by cross multiplying:
9 x 8 = 72
This is considered the fraction on the left's value.
You do the same for the other side:
10 x 7 = 70
This is considered the value of the fraction 7/8
72 has a greater value than 70.
Therefore, 9/10 is larger.
The answer would be 25 because all of the others are prime numbers, meaning they can only be divided by themselves and 1. So it would be C.
The answer should be obtuse. I'm not sure why it is saying it's incorrect but none of the other answers make sense.
