Answer:
9
Step-by-step explanation:
y=x
y=kx
substitute k for 0.75 and x for 12 in the above equation
y=0.75×12
y=9
15 miles per hour = 22 feet per second
Answer:
a) x = 69°
b) y = 69°
Step-by-step explanation:
a. Given that AB and CD are parallel lines, therefore:
x = 69° (alternate interior angles are congruent to each other)
b. y + 111° = 180° (consecutive interior angles are supplementary)
y = 180° - 111° (substraction property of equality)
y = 69°
Answer: x = 6
Step-by-step explanation:
(3)(2x) = 6x
(3)(4) = 12
12-12 cancels out
72-12 = 60
6x/6 cancels the 6 out
60/6 = 6
x = 6
