Amusical instrument company reduced the time it takes for a worker to build a guitar. before it the reduction it took 5 hours. now in 7 hours they can build 3 guitars. by how much did the reduce the time it takes to build each guitar? show equation and solution.

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).

What can you determine about the solutions of this system

Ineed i been stuck on this question since yesterday
