Step-by-step explanation:
5/6 * 18
Rearranging
5 * 18/6
5 *3

The answer is 28 %, this is the percent of the class with blue eyes.
A product is the result of multiplication.
A quotient is the result of division.
So you're trying to find the quotient of a number (x) and 5 that equals 8.
Try plugging in the answers.
x/5=8
A. x=4
4/5=8 (Incorrect, 4 divided by 5 is 0.8)
B. x=8
8/5=8 (Incorrect, 8 divided by 5 is 1.6)
C. x=40
40/5=8 (Correct, 40 divided by 5 is 8)
D. x=80
80/5=8 (Incorrect, 80 divided by 5 is 16)
So your answer is C. 40
The quotient of 40 and 5 is 8.
3x^2 + 6x - 10 = 0
3(x^2 + 2x) - 10 = 0
3[ (x + 1)^2 - 1 ] - 10 = 0
3(x+1)^2 - 13 = 0
so the vertex is at (-1,-13)
the roots will be same distance from x = -1
that is a distance 1.08 --1 = 2.08
so other root is approximately -1 -2.08 = -3.08
the other intercept is at (-3.08,0)
So you can buy $4 pack of $800 each, or buy $7 packs of $500 each.
