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: 2.66 hours
Step-by-step explanation:
Shawana can paint a fence in 8hours which means in one hour she can paint 1/8 of a fence.
Kevin can paint the same fence in 4 hours, so in one hour he can paint 1/4 of the fence.
Together in 1 hour they can paint 1/8 + 1/4 = 3/8
Total hours for painting is 3/8 or 2.66 hours
Here's an example of %
20% = 0.2
2% = 0.02
when multiplying with decimals in place you always add up the two periods, 155.8 × 0.2 = 31.16
since the dot is one over for both you add 1 + 1 which equals 2, then when you get 31.16 you move over 2 decimal points, making it 31.16
btw the answer is when you subtract 31.16 from 155.80 which would be 124.64$ for your final cost.
100 ; you are adding 20 every time, therefore if you add 80 plus 20 you get 100. :)
This is the correct answer is
