Question

I NEED HELP PLEASE HELP ME!
Brad can make 4 key chains in an hour. Velma can make only 3 key chains in an hour, but she already has 6 completed key chains. Explain to Brad how he can use a system of equations to determine when he will have the same number of key chains as Velma. Use complete sentences.

@butterflydreamer can you help me? No one won't help me

Answer 4

let x = key chains per hour, B = Brad, V = Velma

Brad can make 4 key chains in 1 hr.
This means B = 4x

Velma can make 3 key chains in 1hr but she already 6 completed key chains... so this means you need to ADD 6.
V = 3x + 6

If he wants to make the same number as Velma.. this means we want Brad = Velma right?
So B = V
We know B = 4x, V = 3x + 6
So since they must be equal to each other ( B = V).. we have:
4x = 3x + 6

Now we solve for x..

Thank you so much!!!!!

Answer 6

you're welcome :)

Answer 7

Slight mistake though, x should be number of hours and not key chains per hour,
because key chains per hour is given both for Brad and Velma
if brad can make 4 key chains in 1hour, in x hours he will make 4x key chains
similarly for Velma we have 3x+6, equate both these and calculate x, this will be the number of hours Brad will need to work to catch up to Velma

ooops, my mistake but yes that's true! :)
