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.
Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
Answer:
x=21/40
Step-by-step explanation:
First get common denominators
3/8 *5 to top and bottom is now 15/40
3/20 *2 to top and bottom is now 6/40
isolate the X
x-15/40=6/40
+15/40 +15/40
x=21/40
Answer:
Money
Step-by-step explanation:
This is really dumb, but a person can be in debt by 20 cents and another person by 10 cent; therefore, the person who is in debt by 10 cent obviously has to pay less than the person with the 20-cent in debt. Given these facts, the person in debt with one cent has more money then the person in debt with 20 cents.
