Accepted Solution

A:
30 Divided by What Equals 5? 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 can we divide 30 by to equal 5? Solving 30 Divided by What Equals 5 Here’s how you would set up this question as an equation: 30 x = 5 \frac{30}{x} = 5 x 30 ​ = 5 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, it can be done in two steps. The first step is to multiply both sides by x to isolate 30: 30 = 5 ∗ x 30 = 5*x 30 = 5 ∗ x Then we can isolate x on the right side of the equation by dividing both sides by 5: 30 5 = x \frac{30}{5} = x 5 30 ​ = x When we simplify the new equation, we can solve for x. In this example, we will round to the nearest three decimal places if that’s needed. x = 6.000 x = 6.000 x = 6.000 Practice Other Division Problems Like This One If this problem was a little difficult or you want to practice your skills on another one, give it a go on any one of these too!
