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.

Best ResponseYou've already chosen the best response.0So a systems of equations solves for when two things are the same, in this case when the number of bracelets made is equal

Best ResponseYou've already chosen the best response.0it says she can make 4 in an hour. so every hour is 8 key chains.

Best ResponseYou've already chosen the best response.0Brad makes 4 per hour, so the number of keychains after x hours is 4x. Velma makes 3 per hour, so her number should be 3x, but she started with 6, so we must add that.. After x hours, she will have made 6 + 3x, while brad will have made 4x To solve when the number of bracelets will be the same, we will have to find x. The # of bracelets will be equal when both equations equal each other, so when 3x + 6 = 4x

Best ResponseYou've already chosen the best response.0what you mean is every i houre she/he makes 4 and if you add 4+4 it =8. and when he makes 8 that is an equivilant of one hour

Best ResponseYou've already chosen the best response.0You start by reading Brad can make 4 key chains in an hour. and this sentence 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. "when he will have..." means they want us to find time (in hours) if we want to find hours, give it a "name" like "x" x is the number of hours when both people have the same number of chains.

Best ResponseYou've already chosen the best response.0Now back to Brad can make 4 key chains in an hour. if Brad works for 1 hour, how many chains will he make? if he works for 2 hours? for 3 hours? for x hours? (you get the answer by multiplying rate * time, or in this case 4 * x) if you let y be the name for "number of chains", you write y=4x and that is short for y (number of chains) is 4 times number of hours worked

Best ResponseYou've already chosen the best response.0now try to do the same kind of thinking for Velma Velma can make only 3 key chains in an hour, but she already has 6 completed key chains.
