Answer:
O x<40
Step-by-step explanation:
D
a direct linear variation equation has the form f(x) = kx
f(x) = x - 12 is not in this form thus does not show a direct linear variation
Answer:
x + 111 + 42 = 180 ( sum of all measures is 180 degree)
x + 153 = 180
x = 180 – 153
x = 27 degree
Answer:
if x is what you are looking for then, x = 30
Step-by-step explanation:
3x - 40 = x + 20 (they are vertically oppositel
2x = 60
x = 30
