Jacob can create an app in 24 hours, but if he works together with a friend they can create an app in 16 hours. how long would it take for his friend to create this app alone?

Time taken by his friend to create the app alone = 48 hours.

Step-by-step explanation:

Hours needed by Jacob to create an app = 24 hours

Let hours needed by his friend in creating the app alone = x hours

The both can create the app in 16 hours.

Hence, Time taken by his friend to create the app alone = 48 hours.

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
