Q:

What Divided by 2 Equals 18?

Accepted Solution

A:
What Divided by 2 Equals 18? Methods Setting up the problem: In a problem like this, the “what” means that we’re working with a variable. The most common variable used in math is “x”. So, we could say what number, x, when divided by 2, equals 18? Solving What Divided by 2 Equals 18 Here’s how you would set up this question as an equation: x 2 = 18 \frac{x}{2} = 18 2 x ​ = 18 The goal of the problem is to solve for x. To do this we need to change the equation so that x is alone on one side of the equation.In this case, we can do that by multiplying both sides of the equation by 2, resulting in this equation: x = 18 ∗ 2 x = 18*2 x = 18 ∗ 2 Then we simplify and find our answer: x = 36 x = 36 x = 36 So, the answer to the question “What divided by 2 equals 18?” is 36.To prove this, we can take the original problem: x 2 = 18 \frac{x}{2} = 18 2 x ​ = 18 And insert 36 in the place of x: 36 2 = 18 \frac{36}{2} = 18 2 36 ​ = 18 Because this is true, the answer must be correct.
