Answer: 450
Step-by-step explanation:
971 = B + (T+71)
971-71 = 2 B
450 = B
Okay so I wont be able to show the row here but I will try my best.
7(5x-4y=28) = 35x-28y=196
-5(7x+5y=18) = -35x-25y=-90
= -53y=106
= y=-2
5x-4(-2) =28
5x+8=28
5x=20
x=4
2 slices are left left because if you change the 8 to a fraction it will turn to this 8/8 and you need to change 3/4 to have the same denominator as the 8/8 so 3/4 will turn to 6/8 and then you subtract 8/8 by 6/8 and itll be 2/8 left so the answwer is 2 slices left
