Answer:
Step-by-step explanation:
x + y = 180
3x = y
x + 3x = 180
4x = 180
x = 45
3*45 = y
y = 135
The two angles are
45
135
Answer:-6x^2-12x-3
Step-by-step explanation:
assume the equation is ax^2+bx+c=y
c=-3
-b/2a=-1
a-b+c=3
a=-6
b=-12
When you think <em>least common denominator</em>, what you should really be thinking is <em>least common multiple</em> of the denominators.
In this case, our denominators (bottom numbers) are 25 and 10.
Let's find the LCM.
multiples of 10: 10, 20, 30, 40, 50...
multiples of 25: 25, 50, 75, 100...
The LCM/LCD is 50.
O=ollie
O-8=3O-16
-8=2O-16
8=2O
4=O
ollie is 4
