Coach Macias needs to buy socks and cleats for five members of his soccer team. The price of the socks is $35 for 5 and the price of cleats is $250 for 5. Coach Macias ends up buying $320 worth of socks and cleats. Write an equation that represents the relationship between the number of socks, x and the number of cleats, y, that Mr. Shirt bought.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.

What is the rest of the question?
