You're writing a book about a $3,030 bike race across the United States. You wonder about a title, and how many pedal strokes it takes to finish the race. Assuming a pedal stroke is about 16 ft on average which of the following would be the best title?

I hope that helped.

Step-by-step explanation:

We have that a mile is equal to 5280 feet. Hence the whole distance is 15.998.400 feet in distance. Since every 16 feet we have one stroke, we have to divide the distance by 16 to get the number of strokes. The result is 999.900 strokes. Hence, if one wants to be accurate, the correct title is "999.900 pedal strokes". For poeticness though, maybe the best title is "1 million pedal strokes".

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

did u ever get the answers? i need
