4 There were 822 students signed up to run in timed races. If exactly 6 students ran in each race, how many races were there?

137 races

Step-by-step explanation:

822/6=137

so if there was 822 people and the limit for the races were 6 people, there would have to be 137 races for all the people.

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
