Answer:
BCG =65
Step-by-step explanation:
DCG + GCB = DCB
We know BCG = 31x+3 and GCD = 12x+2 and BCD = 91
Substituting these in
12x+2 + 31x+3 = 91
Combine like terms
43x +5 = 91
Subtract 5 from each side
43x+5-5 = 91-5
43x = 86
Divide by 43
43x/43= 86/43
x=2
BCG = 31x+3
=31(2)+3
=62+3
=65
Mr.Jackson is incorrect because 0.75 is per pound it's not whats added onto 8 pounds
It is more than 0, because you cancel the x, and you get 2+5, which is 7
Add 12 to each side
so it should be C>8
