How to solve Two-Step Equations?
Two-step equations involve two math operations - one operation is addition or subtraction. The second operation is multiplication or division.
To solve a two-step equation, follow the order of operations backwards - add or subtract, then multiply or divide to solve for x.
Example 1: Solve for x.2x-1=3 2x-1+1=3+1 First we add 1 to both sides of the equation.2x=4 2x/2=4/2 Now we divide both sides of the equation by 2.x=2
Example 2: Solve for x.x/2 +1=7 x/2+1-1=7-1 First we subtract 1 from both sides of the equation.x/2 =6 2.x/2=2.6 Now we multiply both sides of the equation by 2.x=12
Evaluate the area and perimeter of a square: Example: Calculate the area and perimeter of a square with a = 5´. Be sure to include units in your answer. Solution:
A 'woman was trying to teach her three-year-old child the numbers from 1to 5 from a children's book on numbers. Each number was illustrated by the same number of trees drawn next t
Q. Determine Z-scores and Percentiles? Ans. Z-scores help measure how far a piece of data is from the mean. More specifically, Z-scores tell how far a piece of data is fr
Mean Value Theorem : Suppose f (x) is a function which satisfies both of the following. 1. f ( x )is continuous on the closed interval [a,b]. 2. f ( x ) is differentiable on
I am comparing building a house and buying a house. which one of the option you would choose.
HOW MANY TENS ONES AND HUNDRED ARE IN A GROUP OF 2
Explain Histogramsin details? Another way to display frequencies is by using a histogram. The following is an example of a histogram using the data from the previous example:
Describe Order of Operations with example? The order of operations is a set of rules that describe the order in which math operations are done. Try doing this math problem:
Mathematical Problem Solving In 1945, mathematician George Polya (1887-1985) published a book titled How To Solve It in which he demonstrated his approach to solving problems.
