Using the equation w times open paren 1 point 5 plus 1 close paren plus 2 is equal to 17 , the race’s organizer determined the cyclists will need to ride 9 laps before the sprint to the finish. Which explains the error?
Answer
A
The solution should be 8 , and the cyclists will need to ride 8 laps before the sprint to the finish.
B
The solution should be 6 , and the cyclists will need to ride 6 laps before the sprint to the finish.
C
The equation should be 2 times open paren 0 point 7 5 w plus 0 point 5 close paren plus 2 is equal to 17 , and the cyclists will need to ride 21 laps before the sprint to the finish.
D
The equation should be 0 point 7 5 w plus 0 point 5 w plus 2 is equal to 17 , and the cyclists will need to ride 12 laps before the sprint to the finish.
Explanation
Combine the terms inside the parentheses: 1.5 + 1 = 2.5. Then 2.5w + 2 = 17, so 2.5w = 15 and w = 6. The organizer’s result of 9 laps is incorrect; the cyclists should ride 6 laps before the sprint to the finish.
