How can we find the height of a triangle if it is not a right triangle?
If we draw a line straight down from our highest vertex to the base we split our triangle into two right triangles. We can then use the Pythagorean theorem in order to find the height of the triangle.
How can we tell if two fractions are the same?
We can tell if two fractions are the same if they both reduce to the same number. We can reduce fractions if both the numerator (top) and the denominator (bottom) can be divided by the same number. If after reducing as much as possible we end up with the same fraction they are the same.
How do you solve multi-step equations?
The most important thing to remember when solving a multi-step equation is that both sides of the equation must remain equal to each other. So we first want to make each side as simple as possible by combining like terms on each side. Our end goal is to get our variable all by itself so we must next "move" all terms containing our variable to one side and all other terms to the other. We "move" terms by add or subtracting them to both sides, so that the side it was originally on cancels out. Once all terms containing the variable are on the same side we must divide each side by the coefficient that accompanies the variable.
