Answer:
A, 12.5
Putting them in order was this:
10, 11, 11, 11, 12, 13, 13, 15, 15, 17
and the median is between 12 and 13, which is 12.5
(Hope that helps you. ^^)
These are the steps to solve this question. and I used Substitution to explain it.
1. Identify what you need.
2. Write out your two different equations.
30e + 115h = 1457 and e + h = 18
3. Identify witch way you would proceed. Substitution or Elimination.
4. Solve using you prefers way. for me I will use substitution. find either e first or h. this doesn't matter witch you start with.
5. Take one of the equations and get a variable alone. TIP: use the one share that variable stands alone.
6. When variable is alone. put what ever it equals on the other equation and solve. Do this once.
7. When solved take that answer and plug it into its desined spot and solve to find the other answer.
8. Alone both solutions from the answer to what e and h are.
X>7→because if x=7 the answer is 8 so it should be >7
x<-1→if 2|-1-3|=8. →-2 &-3&-4&...are smaller than -1→x<-1
The top rectangle would be 3 times 11 giving you 33
the bottom smaller one would be 3 times 2 for 6 feet
in total you would get 39 feet
Answer:
33 cm
Step-by-step explanation:
9 cm + 7.5 cm + 9 cm + 7.5 cm
