A robot can complete 7 tasks in 3 4 hour. Each task takes the same amount of time

a. 3/28 hours

b. 9 tasks

Step-by-step explanation:

a. The robot can complete 7 tasks in 3/4 hours.

The number of hours it will take to complete one task is:

= Time taken / Number of tasks

= 3/4 ÷ 7

= 3/4 * 1/7

= 3/28 of an hour

b. If the Robot can complete one task in 3/28 of an hour, in one full hour it will complete:

= 1 ÷ 3/28

= 9.33

= 9 tasks

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
