Answer:
x=5
Step-by-step explanation:
19x and its vertical angle are equal. Lets call that angle y
<y and 17x are same side interior angles. Same side interior angles add to 180 if the lines are parallel. Since l is parallel to m.
<y + 17x=180
We know that y and 19x are equal since they are vertical angles, so we can substitute this in.
19x+ 17x = 180
Combine like terms.
36x = 180
Divide each side by 36
36x/36 = 180/36
x = 5
6y = 24 -3x
divide both sides by 6.
y = (x)/2 +4
The selling price would be $11.20.
40% = 40/100 = 0.4
The mark up is 40% of the cost; this means 40% of 8:
40% of 8 = 0.4(8) = 3.20
8 + 3.20 = 11.20
Answer:
R: √(13)
Step-by-step explanation:
Distance formula:
r^2 = (x-h)^2 + (y-k)^2
Center: (h,k)=(-1,5)
Circle: all points of (x,y)=(-3,2)
r^2=(-3+1)^2 + (2-5)^2
r^2=(-2)^2 + (-3)^2
r^2= 4 + 9
r^2=13 ((r^2)^(1/2)) = 13^(1/2) = 3.6055
