What are the answers to the one step equations problem

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).

You decide instead to take the train there. the train will take 135 minutes. convert this into hours and minutes.

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)
