We want to isolate "m" on one side of the equation and have a number on the other side. Let's start by subtracting both sides by 5m
Now, let's subtract both sides by 11
We now have the value of m.
The next thing I'm going to do is a bit tedious, but you typically want to have the variable on the left side of the equation in the field of math. It's a good habit to develop now.
Thus, the answer is choice 3, -18. Let me know if you need any clarifications, thanks!

Answer:
21.98
Step-by-step explanation:
c=
2(3.5)
You need to find the average length. You use the two numbers that gave you the range. (4.5-2.5)/2+2.5 = answer
<span>
so (4.5-2.5)=2 now 2/2=1 1+2.5=3.5mm

(Remember PEMDAS) order of operations is important!! </span>
So first you need to find a formula for who has what!
Because nobody said what chase had, chase is our variable!
Chase = x
Sophie = x-6 (six less than Chase so subtraction)
Jonah = x•3 (three times the amount of Chase)
Now you will put all of this in an equation- adding everybody together! The total is 89 so that will be what’s after the equal sign!
Your equation: x+x-6+x•3=89
First you will use PEMDAS, since there are no parentheses or exponents- you’ll do multiplication first!
x+x-6+(x•3)=89
When you multiply that out, you will be left with: x+x-6+3x=89
Second you will add all common terms! Remember- the 3x means there are THREE x’s in that one spot. Take out all x’s in the equation and add them together!
x+x+3x=5x
Now you are left with:
5x-6=89
Now you will solve this like a regular equation! First, you have to move the -6 to the right so you will do the inverse operation (the opposite sign) and add 6 to both sides! 89+6 is 95 and -6+6 is 0, so the 6 on the left cancels out and isn’t there anymore!
Now you have 5x=95. To get the x by itself, you will divide both sides by 5! (Once again, doing the inverse operation! Since 5 and x are being multiplied, you have to divide.)
When you divide, you are left with x=19. In this question, the answer is:
Each person has $19.
