# Week 17 – Math 10

This week in math 10, we learned Arithmetic Sequences. An arithmetic sequence is a list of numbers with a definite pattern. First we are going to start with a equation 10,8,6 Let’s say we have to determine and We can know that d is 2. And then, we can figure out using it. After that, we […]

# Week 16 – Math 10

This week in math 10, we were focused on solving problem application of systems such as number, money, mixtures, distance, and speed. Therefore, today I am going to show you how to solve money problems. Example 1. Four pencils and two erasers cost $3 .50. At the same prices, two pencils and five erasers cost […]

# Week 15 – Math 10

This week in math 10, we learned solving systems of linear equations. We can solve systems by Graphing, Substitution and Elimination. So, I am going to show you how to solve systems by Elimination that is my favourite method. In the elimination method you either add or subtract the equations to get an equation in […]

# Math 10 – Week 14

This week in math 10, we started unit 9 and learned about system of equations. A system of equations is a collection of two or more equations with a same set of unknowns. Example: two equations that share the variables x and y x + y = 6 2x + y =8 Those two equations are […]
