Q2 - r2+ 3s
if q = 9, r = -6, s = -20
how do i solve this?

-9(2)-(-6)(2)+3(-20)

(−9)(2)−(−6)(2)+(3)(−20)

=−18−(−6)(2)+(3)(−20)

=−18−(−12)+(3)(−20)

=−6+(3)(−20)

=−6+−60

=−66

step-by-step explanation:

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
