Answer:

Let the number be x

Given:

11 + 5x = 20 + 2x

5x - 2x = 20 - 11

3x = 9

x = 3

The number is 3.

Answer:

Step-by-step explanation:

Let x represent the number, and set up an equation:

5x + 11 = 2x + 20

Solve for x:

5x + 11 = 2x + 20

3x + 11 = 20

3x = 9

x = 3

So, the number is 3.

Answer:

3/4

Step-by-step explanation:

The zero at the end of the number is not important, so you are left with 0.75

Basically, you can think of it as 75 is three-fourths of 100, so the fraction would be 3/4. (and 3/4 is completely simplified)

Pani-rosa [81]

Answer:

Step-by-step explanation:

Let's call the number x.

$\dfrac{x}{2}+3=10$

Subtract 3 from both sides:

$\dfrac{x}{2}=7$

Multiply both sides by 2:

$x=14$
