Answer:
(C) 5
Step-by-step explanation:
x+7=2y
<em>Subtract 7 from both sides</em>
x=2y-7
2y-7=x
<em>Multiply both sides by 2</em>
4y-14=2x
y=2x−1
<em>Add 1 to both sides</em>
y+1=2x
<u>Combine equations:</u>
y+1=4y-14
<em>Add 14 to both sides</em>
y+15=4y
<em>Subtract y from both sides</em>
15=3y
3y=15
<em>Divide both sides by 3</em>
y=5
<u>The answer is </u><u>(C) 5.</u>

Answer:
the correct answer is marked
Step-by-step explanation:
When the graph of the left side of the equation does not intersect the graph of the right side of the equation, there are no solutions.

<em>Additional comment</em>
Even if you extend the domain to complex numbers, there are no solutions. The f(x) = |x| function always returns a positive real value, even for complex numbers.
Step-by-step explanation:
Here is the answer to the question
Step-by-step explanation:
1..x=110/2. ( inscribed angle is half of central angle)
2..given,
in triangle DFE
angleDFE=angle DAE ( inscribed angle on same arc are equal)
angle DFE=55°
angle EDF= angle FED (base angle of isosceles triangle r equal)
now,
angle EDF+angleDFE+angle FED =180°{ sum of angle of triangle)
z+z+55=180°
2z=180-55
z=125/2
z=62.5°
3.. y=90°{ angle at circumference of circle by center is 90°}
hope it helps.

Let's thing
949 ----- 100% of the price
499 ------ x% of the price
Multiply in cross
949.x = 100.499
949x = 49900
x = 49900/949
x = 52,58%
So, rounding it 52,58% ≈ 53%
