Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
To isolate n, we want to subtract 7/9 from both sides.
11/6 - 7/9 = n
To subtract these fractions, they need to have the same denominator. A common multiple of 6 and 9 is 18.
11/6 ⇒ 33/18
7/9 ⇒ 14/18
33/18 - 14/18 = 19/18
n = 19/18
Hope this helps!
Let’s assume the point in the centre is the origin of the circle.
This means the radius is 21/2 = 10.5cm.
180 - 168 = 12 degrees as the angle between BC.
Circumference of a sector is:
Angle/360 • pi • diameter
=12/360 • pi • 21 cm
= 2.19 cm = 2.20 cm
Which is option B
6n - 10 = 4n + 6
6n - 10 + 10 = 4n + 6 + 10
6n = 4n + 16
6n -4n = 4n - 4n + 16
2n = 16
2n/2 = 16/2
n = 8.
The solution is that the value of n = 8.
