If you need to you can write it out. the answer is X=14
C. 427
The median is the middle number of all the data
Since there is an even number of data points the median is in between the middle two data points (434 and 420)
To find this: 434-420=14
14/2=7
434-7=427
420+7=427
Answer:
7/8
Step-by-step explanation:
Start by finding a common denominator. In this case you can turn the 4 into an 8 by multiplying by 2 but you have to do the same to the 3
2(3/4)= 6/8
Step 2: Add 6/8 + 1/8
6/8+1/8= 7/8
Answer:
8,5,2
Step-by-step explanation:
8 , 5, 2 Just use rigorous trial and error
|DF| = |DE| + |EF|
|DF| = 9x -36
|DE| = 47
|EF| = 3x+10
Substitute:
9x - 39 = 47 + 3x + 10
9x - 39 = 3x + 57 |+39
9x = 3x + 96 |-3x
6x = 96 |:6
x = 16
Put the value of x to the equation |EF| = 3x + 10
|EF| = (3)(16) + 10 = 48 + 10 = 58
Answer: |EF| = 58
