Answer:
Don't worry, there is no solution.
Step-by-step explanation:
If you end up with 0 equaling something that isntn0 when you're simply solving a variable, there is no solution. But if you get 0=0, it's all real numbers.
Answer : Explained.
Step-by-step explanation: As given in the question and shown in the attached figure, ΔABC be the large triangular stone that Mei wants to divide into four smaller triangular stepping stones in a pathway.
Let D, E and F be the mid-points of the sides BC, CA and AB respectively. Then, DE, EF and FD are the mid-segments of ΔABC.
Then , we have
4 × Area of ΔDEF = 4 ×Area of ΔFBD = 4 × ΔAFE = 4 × Area of ΔECD = Area of ΔABC.
Thus, we have
ΔDEF ≅ ΔFBD ≅ ΔAFE ≅ ΔECD.
Thus, in this way, cutting along mid-segments creates four congruent stepping stones.
To find the mean of a data set, you have to add all of the numbers and divide by the number of data.
So
50 + 54 + 62 + 48 + 49 + 52
To get 315.
315 divided by 6 is 52.5
So the mean of he data set is 52.5
Hope this helps :)
Answer:
x = 8
Step-by-step explanation:
7x + 2(6x + 9) = 170
2(6x + 9) = 12x + 18
7x + 12x + 18 = 170
19x = 152
152/19 = 8
x = 8
