a. Joelle has y = 18 + 4x, where x represents the number of weeks.
b. Lewis has y = 30 + 3x, where x represents the number of weeks.
c. To find when Joelle and Lewis have the same number of rocks, we can set their equations equal to each other: 18 + 4x = 30 + 3x.
d. To find the number of rocks when the collections are equal, we substitute the solution from part c into either equation: y = 18 + 4x (where x is the number of weeks).
joelle currently has 18 rocks in her collection and gains 4 each week. lewis currently has 30 rocks in his collection and gains 3 each week. set up a system of equations to show how many rocks each has in their collection.
a. joelle has y= _x+_
b. lewis has y=_x+_
c. after how many weeks will joelle and lewis have the same number of rocks in their collection? _ weeks
d. how many rocks will joelle and lewis have when the amount of rocks in their collection is equal? they will each have _ rocks in their collection.
