Jack brought 3 slices of cheese pizza and 4 slices of mushroom pizza for total cost of $12.50. Grace brought 3 slices of cheese pizza and 2 slices of mushroom pizza for total coast of $8.50. The system of equations below represents these facts

3x+4y= 12.51

3x+2y= 8.52

Step-by-step explanation:

Given data

let cheese pizza be x and  mushroom pizza be y

Hence

3x+4y= 12.51

also

3x+2y= 8.52

Hence the systems of the equation is given as

3x+4y= 12.51

3x+2y= 8.52

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
