Question

I need help please I'm stuck,
Use commutative property of multiplication to solve:
2.30b + 1.85(23-b) = 46.60

I'm so confused I'm learning about cost problems and I simplified the equation to there now they want me to distribute and now I'm confused

Answer 1

distribute the 1.85 to the stuff in parenthesis.

For example:
2(2 + x) = 4 + 2x

Answer 2

so 1.85(23-b) = 42.55 +23b?

Answer 3

Almost. It would be 42.55 - 1.85b

Answer 4

Oh I see thank you

Answer 5

I guess I should've used different numbers for my example...
2(3 + x) = 6 + 2x

Answer 6

so now Im down to 2.30b + 42.55 - 23b (im guessing I have to add the like terms now)

Answer 7

2.3b + 42.55 - 1.85b = 46.6

Answer 8

oh okay I think i got it from here thank you <3

Answer 9

so in the end b = 8.1 yes?

Answer 10

no

Answer 11

2.3b - 1.85b = 46.6 - 42.55
0.45b = 4.05
4.05 / 0.45 = 9
b = 9

Answer 12

oh I see I made a mistake simplifying Thank you I can now close this question
