2x^2-7=4
subtract 4 from both sdies
2x^2-11=0
therefor
2x^2=11
divide by 2
x^2=5.5
square root both sdies
x=-2.345 or 2.345
Answer:
$7.20
Step-by-step explanation:
First, we would have to find out how much to subtract from $62.
We need to multiply 90% and 62 or 0.9 x 62
When we finish this equation we get 54.8, which is what we need to subtract from 62 to see what 90% off is.
62 - 54.8 = 7.2, so therefore our answer is $7.20
The correct answer is D. $246.6
(It is actually $246.597 but that is rounded to 246.6)
$189.69 x .3 = 56.907
$189.69 + $56.907 = $246.597
Take .50 and multiply it by 2 because it doubled. then multiply that by 6 or 12 to get your answer
