Answer:
23
Step-by-step explanation:
133 = 18 + 5x
155 = 5x
23 = x
Answer:
x = 14
Step-by-step explanation:
The polygon given has 6 sides
Sum of interior angles of a 6-sided polygon = 180(n - 2)
substitute n = 6 into 180(n - 2)
Sum of the polygon = 180(6 - 2) = 720°
Thus:
10x + 8x - 16 + 12x - 8 + 7x + 2 + 9x + 4 + 6x + 10 = 720
Add like terms
52x - 8 = 720
52x = 720 + 8
52x = 728
x = 728/52
x = 14
Answer
18 hours
Step-by-step explanation:
if 10 people spend 15 hours
one person spend 15/10=1.5
so 1.5 × 12=18hours
The number of ways when the choice is not relevant is 4
<h3>How to determine the number of ways?</h3>
The number of colors are:
Colors, n = 4
The color to choose are:
r = 3
<u>Relevant choice</u>
When the choice is relevant, we have:
![Ways = ^nP_r](https://tex.z-dn.net/?f=Ways%20%3D%20%5EnP_r)
This gives
![Ways = ^4P_3](https://tex.z-dn.net/?f=Ways%20%3D%20%5E4P_3)
Evaluate
Ways = 24
Hence, the number of ways when the choice is relevant is 24
<u>Not relevant choice</u>
When the choice is not relevant, we have:
![Ways = ^nC_r](https://tex.z-dn.net/?f=Ways%20%3D%20%5EnC_r)
This gives
![Ways = ^4C_3](https://tex.z-dn.net/?f=Ways%20%3D%20%5E4C_3)
Evaluate
Ways = 4
Hence, the number of ways when the choice is not relevant is 4
