Answer:
84.37%
Step-by-step explanation:
The nonprofit consumer education organization, named Myvesta, has spent $2252 as an average summer vacation cost.
If $1900 of this amount is charged on a credit card, then the percentage of charged vacation cost will be given by
(Amount charged on a credit card / average summer vacation cost) ×100%
i.e. %
= 84.37% (Answer) { Round to the nearest tenth of the percent}
Step-by-step explanation:
I do not know but I hope you have a great day.
Factor out the 3y²
3y²(3y-5)
4x - 9 = 15
Add 9 on both sides (-9 + 9 cancels out and 15 + 9 = 24)
4x = 24
Divide by 4 on both sides (4 / 4 cancels out and 24 / 4 = 6)
x = 6
<u>The answer is B</u>
