Y = 30/20x + 20
( i haven’t done this in a while but i’m pretty sure this is right)
Supplimentary angles add upto 180 degrees.
Given that angle P is three times angle Q-4 then ;
Let angle P be 3(x-4) = 3x -12
Let angle Q be x
Applying the rule of supplimentary angles;




Divide both sides by 4 to get value of x in degrees

x= 48 degrees
Angle Q = 48 degrees
Angle P = 3x-12 = (3*48)-12 = 132 degrees
Answer:
11x
Step-by-step explanation:
you add the numbers like you normally would and then add the x at the end
3 + 6 + 2 = 11
add the x
11x
2x^2 = 2
so x needs to equal 1 since 2*1 = 2
Answer:
40
Step-by-step explanation:
We can solve this by listing the multiples of the 2 numbers
multiples of 8 : 8, 16, 24, 32, 40, ....
multiples of 10 : 10, 20, 30, 40, .....
The least common multiple of 8 and 10 is 40
