A diagram would be nice. The quick answer is C.
The first answer makes AE 8 which is twice as long as AC. I don't think the intent of the question is to use an external point.
The second one is also incorrect. This time E is in a place such that it makes AC and AE both equal and that too isn't possible.
The third one is the answer because D and E are both 1/2 the distance between the end point of the line containing them.
D is wrong because E is the midpoint of AC but D is not the midpoint of AB.
Answer:
Arlo's weight = 52.3 kg
Explanation:
Let Arlo be "x"
Then,
Arlo = x
Bert = x+20 (Because Bert is 20 heavier than Arlo)
Cassie = x+20-5 (Because Cassie is 5 lighter than Bert)
Donnie =
(Because Donnie is half of Bert's weight)
Average = 57
Step by step Calculations:
57 =
(The whole divided by 4 because the total people is 4)
57*4 = x + x + 20 + x + 20 - 5 + 
228 = 3x + 35 + 
228 - 3x - 35 = 
193 -3x = 
2(193 - 3x) = x + 20
386 - 6x = x + 20
386 - 20 = x + 6x
366 = 7x
x = 
x = 52.3 kg (corrected to 3 significant figures)
Therefore Arlo's weight is 52.3 kg
Answer:
y is 70° and x is 40 °
Step-by-step explanation:
the triangle has two equal sides as shown on the diagram...so the next angle to 110° which is 70° is equal to y....then by calculation y + x should give us 110° so if y is 70 then x is 40.
C+3c is 4c and -4+9 is 5 so your answer is 4c+5
