Rubber Unit
Can someone else a system of equations for this word problem?
A tool company manufactures pliers, scissors and wrenches. In 10 minutes, the company uses 20 units of steel, 30 pieces of aluminum, and 12 units of rubber () on the handles. Each probe consists of 2 units of steel, aluminum and 4 units from 2 units of rubber. Each unit contains 1 pair of scissors, steel, 3 pieces of aluminum, and 1 unit of rubber. Each key consists of 2 units of steel, 1 unit of aluminum, and no rubber. How many of pliers, scissors, wrenches and produced in 10 minutes on the tool companies?
Let the number of forceps, scissors and wrenches in 10 minutes are produced, p, s, and w respectively. Since each pair requires pliers 2, 4 and 2 units of steel, aluminum and rubber respectively. p-generate pairs requires 2p, 4p and 2p units of steel, aluminum and rubber or .. Similarly s produce shearing requires s, 3s and s units in steel, aluminum and rubber, during or w key to generate calls 2w, w and 0 units of steel, aluminum and rubber or .. Add units in steel, aluminum and rubber needed and compared with the number of used yields the following three equations 2p + s + 2w =) 20 (Steel 4p + 3s + w =) 30 (aluminum 2p + S + 0 = 12 (I leave it to rubber) Do you have this system of 3 equations for 3 unknowns p, S and W wants to solve!
