X= number of hours in run
y = number of hours in bike race
9x+29y=85
x+y=5, and y=5-x
Substituting 5-x for y in the first equation, we have 9x+ 29(5-x)=85 and 9x+145-29x=85, then subtracting 145 from both sides to get -20x=-60 and x=3, which is the amount of hours in the running race. Multiply that by 9 miles per hour to get 27 miles
Answer:
the quotient of 3 and 4 subtracted from 25.
Step-by-step explanation:
The correct answer is √313. ( square root of 313 or 17.7)
