If there exist 97,000 grains of salt in a cubic centimeter of salt and a salt silo holds 13 million cubic centimeters of salt. How many grains of salt are there in the silo? (Leave your answer in scientific notation)

We're often advised to take things we hear or read with a grain of salt. We understand that this means we should be skeptical about the information, maybe because the source is obviously biased or the facts are unreliable. But why a grain of salt? Why not a spritz of lemon or a nibble of chocolate?

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
