Answer:
-2.1
Step-by-step explanation:
2.5(x+4)=4.75
or,2.5x+10=4.75
or,2.5x=4.75-10
or,2.5x= -5.25
or,x =-5.25/2.5
or,x= -2.1
∴x=-2.1

Triangles JFE and JLK are similar provided that line segments FE and LK are parallel. This means that corresponding parts of these triangles occur proportionally to one another. In particular,

From this relation we get

Now we can solve for

Answer:
The mean is 44.2
Step-by-step explanation:
1. Add all the numbers: 29+31+35+37+38+44+43+46+46+93=442
2. Divide the sum by the amount of numbers: Since there are 10 numbers in all our equation is 442 / 10 which equals 44.2 and gives us our answer
Answer: your answer is 36.3 cause it's half of 72.6.
Step-by-step explanation:
Answer:
Sum (from n = 0 to n = 33) of 10 + 15 * n
Step-by-step explanation:
The sigma notation is to express an arithmetic series as a summation, in this case we can see that it starts at 10 and ends at 505.
What we can notice is that the values are increasing by 15 units, therefore that will be the proportion that accompanies "n".
Now, we must calculate, how many times is "n", in the final value, for this we subtract the initial value, that is 10 and divide it by 15.
505 - 10 = 495/15 = 33
So "n" goes up to 33
So that series is expressed like this:
Sum (from n = 0 to n = 33) of 10 + 15 * n
