When two-fifths of a number is increased by 15 the result is 27. What is the number?
user100 [1]

Answer:

x = 30

Step-by-step explanation:

Let's set up an equation to represent this problem:

2/5 * x + 15 = 27

subtracting 15 from both sides,

2/5 * x = 12

Multiplying 5/2 to both sides,

5/2 * 2/5 * x = 12 * 5/2

1*x = 30

x = 30
