(x,y) = (r,16)
With this knowledge, plug in r for x, and 16 for y
16 = 2(r) - 4
Isolate the r, add 4 to both sides
16 (+4) = 2r - 4 (+4)
20 = 2r
Divide 2 from both sides
20/2 = 2r/2
r = 20/2
r = 10
hope this helps
Answer:
5 1/2 hours
Step-by-step explanation:
by a factor of 5 means times 4
6*4=24
22/4=5.5 hours
You see how these 2 angles marked are both inside the 2 parallel lines?
And they are on opposite side of the transversal, the line crossing the 2 parallel lines?
These 2 angles are alternate interior angles and they are equal, I think you can do the last part by yourself.
4+8 is 12 so yes it is correct!!!
256.5/18= 14.25
(14.25x2)+(18x2)= 64.5m
