Here is a system of linear equations: 2x + 1 / 2=7

6x - 1/2y = 5

Which would be a more helpful for solving the system: adding the two equations or

subtracting one from the other? Explain your reasoning.

Percy rides his bike 11.2 miles in 1.4 hours at a constant rate. write an equation to represent the proportional relationship between the number of hours percy rides, x,and the distance in miles, y, that he travels.

Which expression is equivalent to 64 - 9x^2?
