Answer: D
Step-by-step explanation:
All would add up to 241 instead of 2.41 because you are not using decimals for the constants (Example: 25q not .25q)
B + N = 18 and 6B + 5N = 101. This is the system of equations you would use.
Let x be the rate of the slower bicyclist and
x + 4 be the rate of the faster bicyclist
Since the bicyclists are headed towards opposite directions, the sum of the distances they covered traveling for one hour and 15 minutes should be equal to 40 km based on the given conditions above. This may be expressed as,
(x)(1.25) + (x + 4)(1.25) = 40
Calculating gives x = 14
Thus, the rate of the bicyclists are 14 km/h and 18 km/h.
Times 3 plus 2.5 is the pattern, and the next number is 383.5
So a kiloliter (kL) is 1000 liters, while a deciliter (dL) is 0.1 liters.
You have 0.0786kL, or 78.6L.
78.6L is equal to 786dL.
