To solve this problem, we should set up an equation, letting the unknown number be represented by the variable x.
2/3x = 20
To solve this equation, we just have to divide both sides of it by 2/3, because we are trying to get the variable alone on the left side of the equation.
x = 30
Therefore, the number is 30.
We would first divide 108/25.18
This would then equal 0.23 as the unit rate.
Answer:
1/3 kg/m3
Step-by-step explanation:
density= mass/volume
mass=40 kg
volume=5m×8m×3m=120m³
density=40kg/120m³=1/3 kg/m³

Answer:
x = 30
Step-by-step explanation:
A straight angle is 180 degrees, meaning the two angles given add up to 180.
5x + x = 180
6x = 180
x = 30
