***ALGEBRA 2*** ***WILL GIVE MEDAL TO YOU AND BECOME FAN*** 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.

let y be the amount of total key chains they have and x be the number of hours in the project how would you set it up after that?

4x = y 4x = 3x - 6

both equations are right but the second equation is what you get after subbing 4x for y
anonymous
  • anonymous
oh yeah thats true
anonymous
  • anonymous
so you would subtract 3x on the right and on the left and your left with x = 6?

oh and one more thing its not 3x-6 its 3x+6 on the first step since she already has 6
acxbox22
  • acxbox22
but yes after you get x=6

oh

so how do i say this when using system of equations

just put the numbers in the equation into words

Let t be the number of hours when the total production of keys from Rad and Thelma are equal. 4t = 3t + 6 t = 6 hours when both workers have produced 24 keys

is that it rob?
acxbox22
  • acxbox22
yep you dont have to solve for the other variable since its not asking for total
