In a diagram OA and OB are two roads where OA=420m, OB=400m and AB=580m. Jim and Huili start to walk from A and B towards O respectively at the same time. Jim speed is 2 m/s and Huili speed is 1 m/s. After a 1 minute and 40 seconds. Jim reaches D and Huili reaches C. a. Find the lengths of OC and OD? b. Find the distance between C and D?

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
