Well for THIS one you'd have to find how many miles he hikes in ONE day, so you would divide 14 by 2 to get 7 miles per day, and to find how many days he hiked in 42 miles, just divide 42 divided by 7 which equals 6, so it took him 6 days to hike 42 miles. =)
I hope I helped! =D
Answer:
The height of the giraffe is 27.432 decimeters.
Step-by-step explanation:
To convert 1 foot to decimeters you would multiply by 3.048.
We need to multiply 9 feet by 3.048 which would give you the answer of 27.432 decimeters.
Let
A-----> 
B-----> 
C-----> 
we know that
Point A-------> Multiply numerator and denominator by 

Point B-------> Multiply numerator and denominator by 

Point C-------> Multiply numerator and denominator by 

Find the distance Point A to Point C

Find the distance Point B to Point C

therefore

Point B is closer to Point C
is closer to 
the answer is
is closer to 
I think you meant to type
4(n)-5=7.
4n = 7 + 5
4n = 12
n = 12/4
n = 3
Linear pair angles have too add to 180, so
5x+9+3x+11=180
8x+20=180
8x=160
x=20
so angle S is 5*20+9 = 109
angle T is 3*20+11 = 71
