after completing a fraction division problem Claire use multiplication to check her answer division:7½ ÷ 1½ = 5 check: 5 × 1½ = 5½

15/2 / 3/2= 15/2 * 2/3= 30/6= 5

5/1 * 3/2= 15/2= 6 3/2= 7 1/2

Step-by-step explanation:

Claire should have made the fractions into improper fraction so she could get the check part right.

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
