Answer: 8

Step-by-step explanation: Speed is distance/time

18/3 = 6 miles per hour running

18/2 = 9 miles per hour biking

3 hour bike = 27 miles

1.50 hour run (0.50 because 30 minutes is half of an hour) = 9 miles

27 + 9/3 + 1.50 = 36/4.5 or 8

The greater of two numbers is six more
pickupchik [31]

Answer:

 

Let's begin by writing the mathematical equations given by the sentences.

 

Let X = smaller number

Let Y = larger number

 

The first sentence tells us

X + Y = 38

 

The second sentence tells us

X = Y/3 + 6

 

Since you weren't given a specific method to use, you can use either the substitution method or the elimination(addition) method, whichever works best for you.

 

Since the 2nd equation has the X isolated, I'm going to isolate the X in the first equation,

X = 38 - Y

 

Since both equations are equal to X, I can set them equal to one another and solve for Y.

Y/3 + 6 = 38 - Y

 

Y + 18 = 114 - 3Y

4Y = 96

Y = 24

 

Then use either of the two original equations to solve for X

X + Y = 38

X + 24 = 38

X = 14
