12 - x = 20 - 5x
You see that -x and -5x both have an 'x' variable? This means they are 'like' terms. To get -x to the other side, we must add (if like terms are on opposite sides, do the opposite of what the sign says, e.g. - will be +)
12 = 20 - 4x
Now move 20 to the other side. Remember, do the opposite! Since 20 is positive, we must minus 20 to the other side.
-8 = -4x
To get x by itself, you will need to get rid of the coefficient of -4. -4x basically means -4 times x, so the opposite of that would be divide! Divide by -4
2 = x (Since both sides have a negative, they cancel out to give a positive)
x = 2

Answer:
C. 1 day
Step-by-step explanation:
Chris:
10 - 4d
Evan:
8 - 2d
How many days will it take before they both have the same number of bags remaining?
Equate both expressions and solve
10 - 4d = 8 - 2d
Collect like terms
10 - 8 = -2d + 4d
2 = 2d
Divide both sides by 2
d = 2/2
= 1
d = 1 day
It will take 1 day before they both have the same number of bags remaining
290
There's 2 hundreds = 200
Then you have 9 in the tens digit.
The only possible answer for the one's digit is 0 since 0 + 9 = 9.
So the answer is 290.
13 hours is the minimum amount of hours he has to work.
