Answer:
x=12 makes (X-12)/(x-8) equal to zero
x=8 makes (X-12)/(x-8) undefined
Step-by-step explanation:
(x-12)/(x-8) = 0
The first step is to multiply each side by x-8
(x-8) *(x-12)/(x-8) = 0 * (x-8)
This cancels the denominator. x≠ 8 because the denominator would equal 0 and then it becomes undefined.
x-12 = 0
Add 12 to each side
x-12+12 = 0+12
x = 12

Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
Answer:
4 times
Step-by-step explanation:
If the smaller container only holds 2 liters, you would have to divide 8 by 2 which is 4.
30:12 divide by 2 = 15:6 divide by 3 = 5:2. There are 5 white for every 2 red (that's as simplified as it gets) :)
