I would be happy to help!
First you need to find the total amount of trees by adding up all of the different trees:
420+160+300=880
Next you need to divide the amount of oak trees by the amount of trees in the woods:
160÷880=0.182 (rounded)
Finally to find the precentage we need to multiply the 0.182 by 100 to get the precentage of 18.2% oak trees.
Graphing is a good method when you have small integers or fractions as your slope.
Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.
Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.
