Answer:
no solution
Step-by-step explanation:
-3x+9-2x=-12-5x\
-5x+5x=-12-9
0=-21
which is impossible.
Answer:
it would be 100
Step-by-step explanation:
if 1=50 and you have 2 then multiple 50 by 2 and that gives you 100
Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.
Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.
Indeed, those two numbers are relatively prime.
So you would just have to divide 20/7 to get the percentage of it.
The answer would be 2.85%.
