Rewrite Equation:
b=8d+9c+3
Hence, the correct answer is b=8d+9c+3
Simplify the expression

It can be simplified as below:

D because if you do a rate problem you do 50 times what equals 100 so times two then you do 32 times two
15+3x-4+6x= 9x+11 add 6+3 then subtract 15-4
3y-4x+8x-y= 4x+2y add -4+8 then subtract 3-1
5x+8x+10x-3x= 20x Add 10+5+8 to get 23 then subtract 3
