Answer:
It will take nine years and four months for the refrigerator to pay for itself.
Step-by-step explanation:
The new refrigerator which costs $1200, saves the family 22% annually in energy cost.
Since the old refrigerator costs $580 to run, we want to determine how many years it will take for 22% of $580 per year to make $1200.
22% of $580
= 580 × 0.22
= 127.6
That is, it saved then $127.6 per year.
Now,
$1200/127.6
≈ 9.4
Which means, it will take 9 years and 4 months for the refrigerator to pay for itself.
Answer:
x=5
Step-by-step explanation:
Ok so put them equal to each other
2x+12=3x+7
subtract 12 from both sides
2x=3x-5
subtract 3x from both sides
-x=-5
divide both sides by -1
x=5

First add your x values and your numbers on the left side
-17x + 6x= -11x
15 + -23= -8
New equation is:
-11x-8= 10-8x
Since you can't have 2 x values on different sides, you have two add the least x value to the other one. -11 is smaller
10 + 3X= -8
Subtract 10 on both sides.
3x= -18
Divide by 3
X= -6
