Answer:
x= 9/20 = .45
Step-by-step explanation:
20x=9
x= 9/20 = .45
Answer:
x = 0.45
Step-by-step explanation:
To solve 20x=9, 20x must be divided by 20 so that it is x by itself. When dividing one side by 20, the other must also be divided by 20, and so 9 should also be divided by 20:
20x ÷ 20 = x
9 ÷ 20 = 0.45
Therefore, x = 0.45
