Jacob walked 0.5 miles in 20 mins what was his average speed in miles per hour?

1.5 miles

Step-by-step explanation:

set up a proportion:

0.5           x

  =

20            60

0.5(60) = 20x

30=20x

(divide by 20 on both sides)

x= 1.5 miles

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
