Solving equation by multiplying or dividing

How do you multiply by dividing?

Multiplying and Dividing FractionsStep 1: Multiply the numerators from each fraction by each other (the numbers on top). The result is the numerator of the answer.Step 2: Multiply the denominators of each fraction by each other (the numbers on the bottom). The result is the denominator of the answer.Step 3: Simplify or reduce the answer.

How do you divide equations?

First, subtract 10 from both sides of the equation: 3x + 4 – 10 = 6y + 10 – 10, or 3x – 6 = 6y. Now divide both sides by 6 for your second step, which gives you 1/2 x – 1 = y. The value of y is 1/2 x – 1.

What is the rule for multiplying and dividing negative numbers?

With two numbers, the rules for multiplying and dividing positive and negative numbers are not only simple, but they’re also the same for both operations: When multiplying or dividing two numbers, if the two signs are the same, the result is positive, and if the two signs are different, the result is negative.

Equation for falling object

What is the equation for free fall? Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. Velocity is defined as gravity x […]
