Mrs. ruiz bought 4 4/5 lbs of strawberries. she used 3/4 of them to bake a pie for dessert. how many lbs of strawberries did she use?

3 3/5 lbs

Step-by-step explanation:

We will multiply the pounds of berries by the faction she used to see how much she used for the pie

4 4/5 * 3/4 = amount used in pie

We need to convert the mixed number to an improper fraction

4 4/5 = (5*4+4)/5 = 24/5

24/5 * 3/4 =

I will change the order to make the math easier

24/4 * 3/5

6 * 3/5 =

18/5

Now we need to change it back to a mixed number

5 goes into 18   3 times with 3 left over

3 3/5 lbs

She used 3 3/5 lbs

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
