Question

Arianys wants to ride her bicycle 55.5 miles this week. She has already ridden 19 miles. If she rides for 5 more days, which equation could be used to determine, m, the average number of miles she would have to ride to meet her goal?
A: 19m=55.5−519 m is equal to 55 point 5 minus 5

B: 5m=19−55.55 m is equal to 19 minus 55 point 5

C: m=55.5−195m is equal to the fraction with numerator 55 point 5 minus 19 and denominator 5

D: 55.5=19m+555 point 5 is equal to 19 m plus 5

Answer 1

The equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C. m = (55.5 - 19)/5

Writing equation

From the question, we are to determine the equation that could be used to determine, m, the average number of miles she would have to ride to meet her goal

From the given information,

"Arianys wants to ride her bicycle 55.5 miles"

and

"She has already ridden 19 miles"

Thus,

The number of miles she needs to ride more is

55.5 miles - 19 miles

= 36.5 miles

If m is the average number of miles she would have to ride for 5 more days to complete her goal,

Then, we can write that  

m = 36.5/5

OR

m = (55.5 - 19)/5

Hence, the equation that could be used to determine, m, is 5m = 55.5 - 19. The correct option is C. m = (55.5 - 19)/5
