Q:

What Divided by 89 Equals 78?

Accepted Solution

A:
What Divided by 89 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 89, equals 78? Solving What Divided by 89 Equals 78 Here’s how you would set up this question as an equation: x 89 = 78 \frac{x}{89} = 78 89 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 89, resulting in this equation: x = 78 ∗ 89 x = 78*89 x = 78 ∗ 89 Then we simplify and find our answer: x = 6942 x = 6942 x = 6942 So, the answer to the question “What divided by 89 equals 78?” is 6942.To prove this, we can take the original problem: x 89 = 78 \frac{x}{89} = 78 89 x ​ = 78 And insert 6942 in the place of x: 6942 89 = 78 \frac{6942}{89} = 78 89 6942 ​ = 78 Because this is true, the answer must be correct.
