C. As that’s the same as 15>8.
For every c substitute 4 and for every d substitute -2
c=4
d=-2
6c + 5d - 4c - 3d + 3c - 6d
= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)
=24+(-10)-16-(-6)+12-(-12)
=24-10-16+6+12+12
=28
It would be 1 copy, and would cost $42.
39+3(1)=42$
30+12(1)=42$
39+3x, 30+12x are the equations
3/6 = 6/x+3
3x + 9 = 36
3x = 27
x = 9
Answer:
B
