Answer:
first one is a and the second one is c
2y - 18x = -26
Add 18x to both sides.
2y = -26 + 18x
Divide by 2 on both sides.
y = -13 + 9x
y = 9x - 13
First of all, you can move the +2x to the other side:
-11 = -26 - 2x
Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x
Then you can divide both sides by 2:
7.5 = -x
Then you can flip the sides and the signs around:
x = -7.5
No, The answer is not -7, it is -7.5
Hope this helps! :)
Charge per day = $90 / 15 = $ 6
<span>Charge per year = $ 6 * 365 1/4 ( If the year contains 365 1/4 days) </span>
<span>= $ 2191.5 </span>
<span>As a percentage = 2191.5 / 1460 * 100 = 150 %
So the answer should be 150%</span>
