George has $15. He would like to know if he has enough money to see a movie ($9.00) and buy a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each). George incorrectly represents the scenario and uses the numerical expression below to decide if he had enough money. 15 - 9 + 2.65 + 1.35 + 2(1.74)

Use the order of operations to simplify the expression.

the perimeter is increased by a factor of 2

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
