Say you are grocery shopping and you come across an item for which the unit price is not labeled. how can you find the unit price on your own?

The correct answer is:

Divide the total price by the number of units.

Explanation:

If we have an item that weighs 12 pounds that costs $24, to find the cost per pound (unit cost) we would divide the total, 24, by the number of units, 12 (since there are 12 pounds in the item). This would give us 24/12 = $2 per pound.

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

98%
