Answer: 
of the mural is sky blue.
Step-by-step explanation:
Let x be the full portion of mural.
Since, 
of mural is painted in shades of blue.
Therefore, the blue portion=
Also, Three eighths of the blue area is sky blue.
Therefore, the portion of the mural is sky blue=
The portion of the mural is sky blue=
Simplify, by dividing numerator and denominator by 4, we get
The portion of the mural is sky blue=
An answer to this would be y=- 1 over 3 x
Answer:
C
Step-by-step explanation:
do that with pithagoras:
20² + 4,5² = x²
400 + 20,25 = x²
420,25 = x²
x = 
x ~ 20,5
Letter C: 20,5 feet
Well, if it was out of 50, it would be 76%.
So the answer might be 50 questions total, but maybe there was 49 questions total.
I would probably go with 50 questions total.
To complete this equation, it is vital to know the slope. To find the slope using points, you subtract the first x from the second, and the first y from the second. This gives you a slope of 4. Then, you must follow point-slope form and choose one of the order pairs to use. You then write y then the negative of your number. Since the number is already negative, you turn it into a positive. On the other side of the "=" sign, you write your slope, 4 distributing to x. Then you write the negative of your x value. Since it is already negative, it turns into a positive. This gives you a final answer of y+1=4(x+2). I realize that this doesn't line up with your fill-in-the-blank answer, so I am sorry if it doesn't work.
