Since E is the midpoint, DE and EF are the same length.
Set the equation DE and EF equal to each other and solve for x.
2x + 4 = 3x - 1
x = 5
Then plug in 5 to find the length.
DE = 2(5) + 4 = 14
EF = 3(5) - 1 = 14
DF = DE + EF = 28
Answer:
I believe that this is the best answer mark brainliest if it is
Step-by-step explanation:
The square root property should have been applied to both complete sides of the equation instead of to select
variables.
N/17 = 70/50
Simplify the fraction on the right
n/17 = 7/5
Multiply both sides by 17 to isolate "n" on the left
n = 119/5
Answer choice (A) is correct.
The median is nine (9). You add each number up, and then you divide by the amount of numbers you have.
The mean is 9.83 according to my calculations.
