- Chuck is 2 inches shorter than his sister, Jan. If j is Jan’s height, write an algebraic expression to represent Chuck’s height.
- 48 – (-6) =
- (-42.6) - (14.2) =
- (-43) - (-4.3) =
- C

Write an algebraic expression

- 15 more than 8 times R
- 13 less than the product of 6 and Y
- Half of T plus 4
- The sum of 12 and the product of 7 and W
- Hilda’s sister is A years old. Hilda is 9 years less than twice the age of her sister.

Answers

- 8R +15
- 6Y – 13
- T/2 + 4
- 7W +12
- 2A - 9

Combine like terms

6.) 6B + 8B + 5B + 3V – 2V

7.) 6G + 5T + 3G – 2T – 4G

8.) 9H + 12H – 13H + 6 + 4J

9.) 6M – 3M – 5M + 8U – 12U

10.) 8K + 2W – 7K + 8 + 4W – 3W - 7

Use the distributive property and combine like terms

11.) 6 (5M + 6G)

12.) 5 (4H – 4L)

13.) 3 (3D + 3E) + 7

14.) 14B + 12B + 5(7Y – 9K)

15.) 11A + 3E + (5E + 2A) + (-5)(5F - 7R)

Answers

11.) 30M + 36G

12.) 20H - 20L

13.) 9D + 9E + 7

14.) 26B + 35Y - 45K

15.) 13A + 8E + (-25F) - (-35R)
