Answer: Option B
Step-by-step explanation:
If the solution is 6 then it means that x=6.
Let's call the missing number <em>y</em>
<em> </em>Substitute x=6 and <em>y</em> into the equation and solve for <em>y: </em>

The options does not show 18, but the option B shows 3x, then if x=6:

The answer is the option B
55% were in the rest of the train. it says "d" though, so I can't tell you the exact number.
Answer:
D, D, A, C
Step-by-step explanation:
Congruent means equal.
T and r are alternate angles
Vertically opposite angles are equal
Y is 47 degrees because since the full angle is 90 degrees, subtract:
90-43 = 47

Answer:
The arc is one-third of the circumference.
Step-by-step explanation:
The area of a circumference = 2πr
C = 2πr ... (1)
If an arc subtends a central angle measuring 2π/3 rad,
The length of the arc = rθ
Given θ = 2π/3
Length of the arc L = r(2π)/3
L = 2πr/3... (2)
L = 1/3(2πr)
Since C = 2πr
L = 1/3C
This shows that the arc is one-third of the circumference.
