### 1-3 Practice: Algebraic Expressions

1. seven less than the number "t" is t - 7

2. the sum of 11 and the product of 2 and a number "r" is 2r + 11

3. Arin has $520 and is earning $75 each week babysitting. Algebraic Expression is 520 +75w

4. You have 50 boxes of raisins and are eating 12 boxes each month. AE is 50 - 12m

Evaluate each expression using the given values of the variables:

5. -4v + 3(w + 2v) - 5w; v = -2 and w = 4

-4(-2) + 3 (4 + 2(-2)) - 5(4) = 8 + 3(0) - 20 = -12

2. the sum of 11 and the product of 2 and a number "r" is 2r + 11

### Adding and Subtracting

When adding or subtracting one number from another, we only have to work with one sign, either a plus (+) sign or a minus (-) sign. So when we have more than one sign right next to each other, how do we decide which one to use?

Here is a chart to assist you:

Try these practice problems by combining pairs of signs and solving.

Be careful :)
