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.
Answer:
D) left a units, down b units
Step-by-step explanation:
Changes close to x, affect the horizontal, left/right movement (but sort of the opposite direction than you would expect.... + left move and - right move)

Answer:
Step-by-step explanation:
Hello,
This is the same method as computing for instance:
We need to find the same denominator.
Let's do it !
For any x real different from 0, we can write:
