Answer:
a) 2x+2x+x+x+x=42
b) x=6
c) 6 cm, 6cm, 6cm, 12cm, 12cm
Step-by-step explanation:
First think of how you'll get perimeter. Since in the question it says you add all of the sides to get the perimeter, you write the variables being added together and equal it to 42. Next, you add all of the x's together, which you would get 7x=42. Then, you divide 7x and 42 by 7, giving you x=6. Finally, you plug in 6 into the x's, making sure to multiply the ones that are 2(6) into 12. To check if this is true, add the sides together and make sure you get 42.
Step-by-step explanation:
First convert the 8 pounds to ounces by multiplying by 16.

Then divide the cost by the total ounces.
128/$12.80=0.10
The price per ounce is $0.10.
