A chain weighs 9 pounds per foot. How many ounces will 5 inches weigh? Round your answer to the nearest tenth as needed.

60 ounces.

Step-by-step explanation:

A chain weighs 9 pounds per foot.

We are to find the number of ounces 5 inches weigh.

First we find how many feet are in 5 inches.

1 foot = 12 inches

how many feet? = 5 inches.

Cross-multiplying gives;

  feet

1 foot of the chain = 9 pounds

feet = how many pounds?

Cross-multiplying gives;

pounds

1 pound = 16 ounces

3.75 pounds = how many ounces?

Cross-multiplying gives;

ounces.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
