Answer:
The number is 6
Step-by-step explanation:
Given:
A number tripled and 6 is 24
To Find:
The Number = ?
Solution:
Let the number be x
The question states that the number is tripled. so lets multiply the number by 3, We get
3x
Then
3x + 6 = 24
On solving the equation we get
3x = 24 -6
3x = 18

x = 6
Since E is the midpoint of DF, DE and EF are two halves of DF. First, let's write down what we know.
DE = 3x + 4
EF = 5x - 2
DE = EF
DE + EF = DF
Now, let's plug our values for DE and EF into our first expression.
3x + 4 = 5x -2
Add 2 to both sides and subtract 3x from both sides.
6 = 2x
Divide both sides by 2
3 = x
Let's plug 3 in for x into DE.
DE = 3x + 4 = 3(3) + 4 = 9 + 4 = 13
DE = EF = 13
We can plug 13 in for DE and EF to get DF
DF = DE + EF = 13 + 13 = 26
