the answer is C, because you solve 2.815-749, and after you divide the result per 4, so it is 1/4
Answer:
The solutions are -0.65 and 4.65.
Step-by-step explanation:
3x^2 - 12x = 9
Divide both sides by 3
x^2 - 4x = 3
To make a square with "x^2 - 4x", you need to have a "+ 4" after it so it can be simplified as (x-2)^2. So add 4 to both sides.
x^2 - 4x + 4 = 7
(x-2)^2 = 7
x - 2 = (square root) of 7
x = 2 (+/-) (square root) of 7.
x = {-0.65, 4.65}
The solutions are -0.65 and 4.65.
hope this helps:)sorry if it doesnt

Step-by-step explanation:
Jack spends 1 1/2 times as long on his homework as Jill .
Jill spends 8 1/2 in doing his home work .
Time spent by jack in doing his homework is jacks time multiplied by Jill’s
That’s
1 1/2 x 8 1/2
Change to improper fractions.
We have,
3/2 x 17/2
Multiply through
51/4 = 12 3/4
Jack spends 12 3/4 hours in doing his homework
