Answer:
There's no direct variation
Step-by-step explanation:

Determine if there's a direct variation between the number and its position
I'll start by giving an illustration of how the triangle is represented using stars (*)

Represent the line number with y and it's position with x
On line 1:
y = 1, x = 1
On line 2:
y = 2, x = 3
On line 3:
y = 3, x = 6
On line 4:
y = 4, x = 10
On line 5:
y = 5, x = 15
Note that, x is gotten by calculating the accumulated number of stars while y is the line number.
Direct variation is represented by
y = kx
Or
kx = y
Where k is the constant of variation
For line 1:
Substitute 1 for y and 1 for x
k * 1 = 1
k = 1
For line 2:
Substitute 2 for y and 3 for x
k * 3 = 2
Divide through by 3
k = ⅔
Note that the values of k in both computations differ.
This implies that there's no direct variation and there's no need to check further.
8750 Meters = 8.75 Kilometers
8.75 Kilometers / 5 Kilometers Per Hour = 1.75 Hours = 1 Hour and 45 Minutes
Hope this helps.
find the total cost of the bus by multiplying 75 people by $36:
75 x 36 = $2,700
Now divide the total cost of the bus by 100 people:
2700 / 100 = 27
It will cost $27 per person.
X=2 shown in the work below.
Each person would receive 6 chocolate truffles and 4 caramel truffles because 126÷21=6 and 84÷21=4.
