If their tray looks the same both times, they will have modeled the associative law. They could put the milk and vegetables on their tray first then the sandwich or they could start with the vegetables and sandwich then put on the milk. Students might think of some examples from their experience such as putting items on a tray at lunch. In this case, it doesn't matter if you add 9 + 5 first or 5 + 6 first, you will end up with the same result. An example of the associative law is: (9 + 5) + 6 = 9 + (5 + 6). It is best thought of in the context of order of operations as it requires that parentheses must be dealt with first. As with the commutative law, it applies to addition-only or multiplication-only problems. The order of the numbers stays the same in the associative law. The associative law or associative property allows you to change the grouping of the operations in an arithmetic problem with two or more steps without changing the result. Most Popular Algebra Worksheets this Week And there is nothing like a set of co-ordinate axes to solve systems of linear equations. Algebra tiles are used by many teachers to help students understand a variety of algebra topics. Solving linear equations is much more fun with a two pan balance, some mystery bags and a bunch of jelly beans. Remember that by teaching students algebra, you are helping to create the future financial whizzes, engineers, and scientists that will solve all of our world's problems.Īlgebra is much more interesting when things are more real. The rest of the page covers some of the main topics you'll encounter in algebra units. We then get right into algebra by helping students recognize and understand the basic language related to algebra. This page starts off with some missing numbers worksheets for younger students. On this page, you will find Algebra worksheets mostly for middle school students on algebra topics such as algebraic expressions, equations and graphing functions. Which equation expressesĢ0.Welcome to the Algebra worksheets page at, where unknowns are common and variables are the norm. Two-thirds the distance between the cities.
One-fourth of the distance between two cities is 100 miles less than Which equation represents this situation?ġ9. The degree measure of Angle A can be represented as 3y +Ģ and of Angle B as 5y. A tile setter is joining the angles of two tiles, A and B, to make aĩ0-degree angle. Which equation could be used to find p, the base price of the pizza?ġ8. The base price of the pizza is pĪnd the extra toppings cost $4.50. Which equation could be used to find f, the cost of the food?Ī. This amount included a 6% tax and an 18% tip, both based on the price of the food. A restaurant meal for a group of people cost $85 total. Name the quadrant, if any, in which each point is located.ġ6. (b) To find the x-intercept of a line, we let y equal 0 and solve for x to find y-intercept, we let x equal 0 and solve for y. (a) The point with coordinates (0,0) is called origin of a rectangular coordinate system. (b) To find the x-intercept of a line, we let.equal 0 and solve for
(a) The point with coordinates (0,0) is called. Multiply and write the result in scientific notationġ3. Covert to decimal notation 5.347 x 10-8ġ2. Covert to scientific notation 0.000000373ġ1. Solution:ĭistance from (2, 3) to the line x + y – 2 = 0ġ0.
The ship has coordinates (2,3) the equation of the other line is x+y=2 find the shortest distance from the ship to the line. Therefore, the given two equations are perpendicular to each other.ĩ. Since multiplying both the slope of the equation = -1/4 × 4 Slope of the equation x + 4y = 7 is -1/4. Decide whether the lines are parallel, perpendicular or neither. Find the midpoint of each segment with the given endpoints. Find the x-and y-intercepts of the following equations. Find the x-and y-intercepts of the following equations.ĥ.
