Brian burns 600 calories while drumming for 5 hours. He burns the same number of calories each hour. How many calories does Brian burn per hour?

120 calories per hour

Step-by-step explanation:

Just divide 600 by 5 to find how many calories he burns in 1 hour.  This gives you 120 calories per hour.

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
