Answer:
1.5
Step-by-step explanation:
okay so what you are going to do first is put a line down where the < is this will separate 3m+18 and 30.
next you want to make the M by itself so you are going to subtract 3 from both sides so 3m-3 and 30-3.
30-3=27
okay now your problem should look like this 18<27
then you are going to divide the problem 27/18
once you divide 27/18 1.5 should be your answer or if you need it in a fraction form your answer will be 1 1/2

Answer:
Step-by-step explanation:
Just multiply the first equation by -1 and then add them together to find x. Should look something like
-2x - y = -7
5x + y = 9
--------------------
3x + 0 = 2
x = 2/3
Now back substitute using either equation to find y. I'll use the first:
2(2/3) + y = 7
4/3 + y = 7
y = 7 - 4/3 = 21/3 - 4/3 = 17/3
Answer:
x=2/3
y=17/3
The correct Answer is D because 8 fives=40 and 10 ones =10 which adds up to 50$ and 18 bills total!
