Up to this point, the only types of numbers you’ve seen have been rational numbers. you can write any rational number as a fraction. the prefix ir means not.

now answer the following questions:

1. what do you think it means for a number to be irrational?

2. can you think of any numbers that are irrational? give one example.

An irration number repeat forever/doesn't terminate

Step-by-step explanation:

some examples are 1.343434343434 (reapeats forever)

3.14159367321(doesn't terminate but doesn't repeat), and √2 are some common examples (they cannot be written as fractions because they do not end)

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
