Answer:
-20 2/5 (2/5 as fraction)
Answer:
p = 16/8 = 2
Step-by-step explanation:
We know that the pencils were divided into 8 groups of 2.
Then the total number of pencils is equal to 8 (the number of groups) times 2 (the number of pencils in each group)
8*2 = 16
The total number of pencils is 16.
Then the operation of dividing 16 pencils into 8 groups is written as:
16/8
And we know that this is equal to 2, then the operation is:
16/8 = 2.
Then the equation is:
p = 16/8 = 2
where p represents the number of pencils in each group.

Answer:
- 18. x = 24.5
- 19. x = 4
- 21. x = 10
Step-by-step explanation:
Corresponding sides have same ratio
Q18
- 7/6 = x / (27- 6)
- 6x = 7*21
- x = 147/6
- x = 24.5
Q19
- (x + 5)/15 = (5x + 1)/35
- (x + 5)/3 = (5x + 1)/7
- 7(x + 5) = 3(5x + 1)
- 7x + 35 = 15x + 3
- 15x - 7x = 35 - 3
- 8x = 32
- x = 4
Q21
- (x + 6)/24 = (2x - 2)/27
- (x + 6)/8 = (2x - 2)/9
- 8(2x - 2) = 9(x + 6)
- 16x - 16 = 9x + 54
- 16x - 9x = 54 + 16
- 7x = 70
- x = 10
The sum of the exterior angle of the polygon is not dependent on the number of sides. It will always take the value of one revolution or 360 degrees. Thus, for the question above, the sum of the measures of the exterior angles of a 9-sided polygon is 360 degrees.
