Answer:
40
Step-by-step explanation:
Angles in a circle add up to 360 degrees.
135 + 145 + x + x = 360
280 + 2x = 360
2x = 80
x = 40
Y=-2 is the correct answer
<span>The first equation is
x + y = 27
For the second equation, there are twice as many girls (y) as boys (x), so you write:
y = 2x
Now you have a system of equations:
x + y = 27
y = 2x</span>
Answer:
D
Step-by-step explanation:
f(x) * g(x)= (3x^2-4x-5)(11x-3)
33x^3-44x^2-55x-9x^2+12x+15
33x^3-53x^2-43x+15
