. You want to buy some rice.
A 7-ounce package costs $2.31. A 12-ounce package costs $4.20.
A 22-ounce package costs $7.04. Which package is the best buy?

The 12-ounce package

Step-by-step explanation:

Divide the ounces by the cost to find out the cost per ounce-

7 ÷ 2.31 = 3.03 per ounce

12 ÷ 4.20 2.86 per ounce

22 ÷ 7.04 = 3.13 per ounce

The twelve ounce package costs the least per ounce

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
