The answer to this problem is “C “
Answer:
I believe it is associative property of addition or commutative
Step-by-step explanation:
I have my work at the bottom but to explain you have to divide 30/12, and I got 2.5. That means 30 is 2.5 times bigger than 12. Because we have to find x, we have to divide 7/2.5, to find what is 2.5 times smaller than 7. That’s 2.8. So, x= 2.8
I think it's 150! Hope this helps :)
