The next number in the pattern would be 14.03.
To find this, note the differences found by subtracting each number from the number that comes after.
4.03 - 2.78 = 1.25
5.78 - 4.03 = 1.75
8.03 - 5.78 = 2.25
10.78 - 8.03 = 2.75
Since each difference goes up by .5 each time, we know we can add .5 to the last difference to find the newest one.
2.75 + .5 = 3.25
Now we have the difference, so we add that to the last number.
10.78 + 3.25 = 14.03
Answer:
The length of DF is 15
Step-by-step explanation:
Since the two lines are equal, which is given by the markings on the triangle, then you can set the two lengths equal and find x.
7x - 13 = 3x + 3
4x - 13 = 3
4x = 16
x = 4
Now that we know x = 4, we can plug into the DF length to find its amount.
DF = 7x - 13
DF = 7(4) - 13
DF = 28 - 13
DF = 15
