Question:

Below are addition problems. Fill in the missing number to complete the equation. 4 + __ = 10 __ + 7 = 12 __ + 2 = 5

Margo K.

Answer:

Let's look at the first problem. 4 + __ = 10. 4 plus something equals 10. Lets do this with our fingers so we can physically see how many digits we are adding to 4. Start with 4 fingers up, and let's count up until we reach 10. 5, 6, 7, 8, 9, 10. We added 6 fingers (or 6 digits) to reach 10. So 4+6=10. Lets look at the second problem. __ + 7 = 12. We are going to start at 7 and count upwards until we reach 12. But this time, practice counting in your head instead of using your fingers. If we start with 7, we then have 8, 9, 10, 11, 12. We counted 5 digits until we reached 12. So, 5+7-12. Now let's looks at the last problem. __ + 2 = 5. Let's start at 2 and count upwards until we reach 5. 3, 4, 5. We counted three numbers to reach 5. So, 3+2=5.

Study Skills

Question:

If you are studying for an upcoming test, what materials would be found on your desk to help you study?

Margo K.

Answer:

First, lets make sure you have a good environment to study in, whether that's at a desk, your kitchen table, or a nearby library. Having a space that is quiet and totally your own will set you up for success. So what materials do you have to help you study? - Notes from class (whether they're on a computer or in a notebook) - Required books for class (these are helpful references to have on hand) - Notebook - Pencil/pen and a highlighter - Post-its - Water bottle (to keep you hydrated :))

Question:

Simplify the following expression: 3(6+x) + 2(x-4)

Margo K.

Answer:

Remember, whatever is inside of the parenthesis must be multiplied with what is outside the parenthesis. 3*6 + 3*x + 2*x - 2*4 Rewrite. 18 + 3x +2x - 8 Simplify by combining like terms. 10 + 5x
