A sheet of plywood was made by gluing 7 sheets of wood together.
2 of the sheets were 0.0625 inch thick and the rest were 0.125 inch thick.
how thick was the plywood?
We can use the equation y=2(0.0625)+5(0.125), y being the thickness of the plywood. I got 5(0.125) because two sheets of the 7 were already used, meaning there are 5 sheets of plywood left over. y=0.125+0.625 y=0.75 Therefore, the plywood is 0.75 inches thick.
