In class of 24 students, 13 students sold over 150 raffle tikets each, and the rest of the class sold about 60 tikets each. the class goal was to sell 2,000 tikets. did they rach their goal?

In class of 24 students, 13 students sold over 150 raffle tikets each and 24-13=11 students sold about 60 tikets each.

1. If 13 students sold over 150 raffle tikets each, then together they sold over 13·150=1950 raffle tikets.

2. If 11 students sold about 60 tikets each, then together they sold about 11·60=660 raffle tikets.

3. All together they sold about 1950+660=2610 raffle tikets. Since 2610>2000, they had achieved their goal.

yes.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

good luck on your studies! : )
