Answer:
The result for this equation is
.
Step-by-step explanation:
-Solve the equation:

-Use Distributive Property:


-Subtract 6x and from 12x :


-Add both sides by 30:


-Then, you divide both sides by 6:


So, therefore the answer is
.
Answer: East
Step-by-step explanation:
Given
A spinner initially pointing towards west is made to move
revolutions clockwise and
revolutions counterclockwise.
After one complete revolution pointer points at the same direction.
So, the net movement of the spinner is

That is 1 and half-revolution counter clockwise
After 1 revolution, direction is same, but after half revolution it points towards east.
The final direction is east.
Answer: x is 20
Step-by-step explanation:
This is ratio
a : c = b : x and d : unknown
a : c = 9 : 12 = 3 : 4 which is 9/12
b : x = 15 : x which is 15 / x
So the proportion will be :
3/4 = 15/x
So Cross multiplying
3x = 90
Divide both side by 3
x = 90/3
x = 20
