2a+b=2a but b can not be 0

Mathematics
1 answer:
Morgarella [4.7K]4 years ago
8 0

Answer:

0

Step-by-step explanation:

this is the only answer because if you subtract 2a from both sides you are left with b=  since there is nothing there, that makes it 0. There is no way to solve this without b=0. (i think its a TRICK question)

Mari makes bows for floral arrangements. She uses 1/8 of a yard ribbon for each bow. How many bows can she make from 2 spools th
GuDViN [60]
First, you need to find out how much ribbon she has total. Because there are two spools, you multiply 24 x 2. The answer for that is 48. Then you have to figure out how many bows she can make. Each bow uses 1/8 of a piece of yard of ribbon, so you can divide 48 by 8. Your answer would then be 6 bows.

Here are the equations.

24*2 = X

X/8 = B

Where X represents the yards of ribbon available and B represents the number of bows that Mari can make.
