Answer:
r=3
Step-by-step explanation:
simplify each side
4r+17=6r+11
Subtract 4r from both sides.
17=2r+11
Subtract 11 from both sides
6=2r
divide both sides by 2
3=r
Answer:
1. always
2. sometimes
Step-by-step explanation:
Two lines are coplanar if they lie in the same plane or in parallel planes. There is ALWAYS a plane which contains two parallel lines (see first attached image for details).
Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes
and

and
- they are parallel, but if you consider the pair of lines
and
, you can see they are not parallel.
150 miles= in 3 hours
150 miles/3 hours
= 50mph
Find the scale between sides xz and gh
18/4 = 4.5
Multiply the length of fh by the scale to find x
6 x 4.5 = 27
x = 27
