The total number of lawns Rocco mowed each week is 1 and this can be determined by forming the linear equation in two variables.
Given :
Form the linear equation to determine the number of lawns did Rocco mow each week.
Let the total number of lawns Carly mowed be 'x' and the total number of lawns Rocco mowed be 'y'. Then the equation represents the situation that Carly mowed 2 more lawns than Rocco each week for 6 weeks is:
[tex]x = 6(y+2)[/tex]
Now, if Carly mowed 18 lawns in 6 weeks then the number of lawns Rocco mowed is:
[tex]18=6(y +2)[/tex]
3 = y + 2
y = 1
So, the total number of lawns Rocco mowed each week is 1.
