The sum of two numbers is 27. the larger number is 6 more than twice the smaller number. what is the number?

Step-by-step explanation:

Let's say the numbers are x and y, and y is larger than x.

x + y = 27

y = 6 + 2x

Substitute:

x + (6 + 2x) = 27

3x + 6 = 27

3x = 21

x = 7

So x = 7 and y = 20.

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.
