Q:

What Divided by 9 Equals 78?

Accepted Solution

A:
What Divided by 9 Equals 78? 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 9, equals 78? Solving What Divided by 9 Equals 78 Here’s how you would set up this question as an equation: x 9 = 78 \frac{x}{9} = 78 9 x ​ = 78 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 9, resulting in this equation: x = 78 ∗ 9 x = 78*9 x = 78 ∗ 9 Then we simplify and find our answer: x = 702 x = 702 x = 702 So, the answer to the question “What divided by 9 equals 78?” is 702.To prove this, we can take the original problem: x 9 = 78 \frac{x}{9} = 78 9 x ​ = 78 And insert 702 in the place of x: 702 9 = 78 \frac{702}{9} = 78 9 702 ​ = 78 Because this is true, the answer must be correct.
