Every week Jim runs 8 miles and bikes 12 miles. Write an ordered pair to represent how many miles Jim runs a bikes in 5 weeks. Use the drop-down menus to complete the sentence!

The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and

b (=y) for 5 weeks.

Step-by-step explanation:

Every week Jim runs 8 miles and bikes 12 miles.

Let the week be represented by w , running miles by r and biking miles by b

therefore

1w= 8r + 12 b

Multiplying both sides by 5

5(1w= 8r + 12 b)

5(1w) = 5(8r + 12 b )

5w= 40r + 60b

Jim runs 40 miles and bikes 60 miles in 5 weeks

The ordered pair ( 8,12) can be written as (40,60) for values of r (=x) and

b (=y) for 5 weeks.

The answer is written in the form (x, y) where x is written before y in the ordered pair. We treat  running miles as x and biking miles as y.
