Option B: is the value of y
Explanation:
It is given that "Two times x is 8 more than y". Writing it as expression, we have,
It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,
To find the value of y, let us solve the two equations using substitution method.
From the equation , let us find the value of x.
Now, substituting in the equation
, we get,
Thus, the value of y is
Answer:
3 tiles will not fit together.
Step-by-step explanation:
Measure of an Interior angle of a polygon =
Here, n = number of sides of the polygon
Therefore, measure of the interior angles of a regular hexagon,
A =
A = 120°
Similarly, interior angle of the regular pentagon,
B =
B = 108°
Now m∠A + m∠B + m∠C = 360°
m∠C = 360° - (120° + 108°)
= 132°
To fit the given three tiles perfectly, interior angle (∠D) of the third Octagonal tile should be 132°.
D =
D = 135°
m∠C ≠ m∠D
Therefore, 3 tiles will not fit together.
