Step-by-step explanation:
34−4x+12x−212x34-4x+12x-212x
Simplify each term.
Combine 1212 and xx.
34−4x+x2−212x34-4x+x2-212x
Multiply the numerator by the reciprocal of the denominator.
34−4x+x2−(2(2x))34-4x+x2-(2(2x))
Multiply 22 by 22.
34−4x+x2−(4x)34-4x+x2-(4x)
Multiply 44 by −1-1.
34−4x+x2−4x34-4x+x2-4x
Find the common denominator.
Write −4x-4x as a fraction with denominator 11.
34+−4x1+x2−4x34+-4x1+x2-4x
Multiply −4x1-4x1 by 4444.
34+−4x1⋅44+x2−4x34+-4x1⋅44+x2-4x
Multiply −4x1-4x1 and 4444.

Answer:
A.) x = 1000 kilowatt-hours
Step-by-step explanation:
Because Micah was charged 113.94 total for the month, this is the y value. We are trying to find x, how much electricity he used. We would start by making the equation: 113.94 = 0.11x + 3.94
Now, we need to get x alone.
(Subtract 3.94 from both sides) 110 = 0.11x
(Divide by 0.11) x = 1000 kilowatt-hours

3b+5r=2 gallons of cabbage red
1r+7b=2gallons of egplant
1 gallon of cabbage sells for 22 (means 2 gallos is 44)
1 gallon of egplant is 26 (means 2 gallons is 52)
3b+5r=44
r+7b=52
r+7b=52
miinus 7b from both sides
r=52-7b
sub 52-7b for r in othe equestion
3b+5(52-7b)=44
3b+260-35b=44
-32b+260=44
minus 260 from both sides
-32b=-216
divide both sides by -32
b=6.75
r=52-7b
r=52-7(6.75)
r=52-47.25
r=4.75
3blue+5r=2gallons
5+3=8
8units=2gallons
4units=1gallon
1unit=1quart
therefor
1 quart of blue paint is $6.75
1 quart of red paint is $4.75
