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:</h2>
<u>You can write it as |0 - x| < 6</u>
<h2>
Step-by-step explanation:</h2>
Suppose we have a number line and you are moving towards left side so we get negative numbers. The same logic applies here. You are moving to left side from 0 for 4 steps. So you can write it as
|0 - x| < 6 where x is your desired number
K) 43.96 - To
Forgot that one
28 + vector b = -12
vector b = -40
vector b has magnitude 40 units in the negative y direction.
Answer:
B
Step-by-step explanation:
The answer would be B, because the y-intercept is positive. To double check I used an online graphing calculator and it is correct.
Hope This Helps! Have A Nice Day!!
