Sure the sin function is an odd function because sin (-Ф) = - sin (Ф)
Example: sin (- 30°) = - sin (30°) = -1/2
6/x= -2/18
Cross multiply. ( Multiply the numerators together ) . ( Multiply the denominators together (.
6*18= - 2*x
108= -2x
Divide by -2 for 108 and -2x
108/-2= -2x/2
x= -54
Answer: x= -54
Answer:
x = 110
Step-by-step explanation:

Let n = number of hikers
y = number of slices of bread per sandwich= 2
x = number of sandwiches for each hiker = 3
T = total number of slices of bread used for "n" hikers
The expression below represents the total number of slices of bread used for "n" hikers:
T = 2 slices *3x sandwiches *n hikers
