Solving equation: 20 + 10% x = 80 2x + 30% x = 9.2 15 + 10% x = 18 [solution] 20 + 10% x = 8020 + 0.1 x = 800.1 x = 60 x = 600 2x + 30% x = 9.2 2x + 0.3 x = 9.22.3 x = 9.2x = 415 + 10% x = 1815 + 0.1 x = 180.1 x = 3 x = 30 a machine tool factory planned to produce 20 machine tools in February, and actually produced 30 machine tools
One simple math question for 100 points!
When five same cubes are put together into a cuboid, the surface area is 48 square centimeters less than the sum of the surface areas of the five cubes. What is the surface area of the cuboid after flattening?
Because there are five cubes
So it's in a row
So the overlap has eight faces
48 divided by 8 equals six square centimeters
So what's the surface area
22 times 6 equals 132 square centimeters
Mouth ten = mouth one = mouth one
Fill in 1 2 3 6 7 8 9 to make the equation hold. A number can only be used once
8+9=23-6=17
