A student desk consists of a desk top and four legs. If one cubic meter of wood can produce 50 desks or 300 legs, there are 15 cubic meters of wood, Make them match (equation of first degree with one variable)
If you can make x tables, you can make 4x legs
So: X △ 50 + 4x △ 300 = 15
X=450
So 450 △ 50 = 9 cubic meters of wood is used for the table top
Table legs use 15-9 = 6 cubic meters of wood
Have a good time
A student desk is composed of a desk top and four legs. If one cubic meter of wood can make 50 desks or 300 legs, and there are five cubic meters of wood, please set up
How many pieces of wood are used to make the legs of the table? How many pieces of square table are needed
How to design and make desktop
50x=300×（5-x）÷4
50x=375-75x
125x=375
x=3
5-3 = 2 cubic meters for making table legs
Can make square table: 3 × 50 = 150 pieces
A student desk consists of a desk top and four legs. If 50 desks or 300 legs are made of 1 cubic meter of wood, there are 15 cubic meters of wood
How many pieces of wood do you use for the table top and how many pieces of wood do you use for the table legs
Let x cube be used as the table top and Y cube as the table leg
X+Y=15
50X=300Y/4
The solution is x = 9, y = 6
