Answer:
m∠BCD = 120°
Step-by-step explanation:
Since the interior angles of a quadrilateral add up to 360°, then we get:
2x+x+2x+x=360°
6x=360°
<em>Divide both sides by 6</em>
x=60°
Since ∠BCD's value is 2x and x is equal to 60°, then ∠BCD is 120°.
Answer:
3rd one
Step-by-step explanation:
15/x = 20/100
15*100 = 20*x
1500 = 20x
1500/20 = 20x/20
75 = x
15/75 = 20/100
the expected number of couples who met online is 75
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y-1=2/3(x-3)
This is the equation of a line into point slope form
where
the point is (3,1) and the slope is m=2/3
using a graphing tool
The graph in the attached figure
Answer:
Alright well to find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept substitute in 0 for x and solve for y
X-intercept: (9/13, 0)
Y-intercept: (0, 1/2) Hope this helps :)
