R=r1+r2
simple
all you have to do is leave r2 by itself...
(r2=??)
by doing so you need to subtract r1 on both sides
R-r1=r2
and by doing so you leave r2 by itself
r2=R-r1

substitute the values and solve for x
Answer:
A. Draw a line from the segment to any point on the fold line.
Step-by-step explanation:
When using the paper folding method to find the midpoint of a line segment we take the following steps:
- Draw a line segment on the tracing paper
- Fold the tracing paper so that the endpoints lie on top of each other
- Mark the intersection of the fold and the segment with a point
These steps include statements B, C, and D. Drawing a line from the segment to any point on the fold line, which is statement A, is not included in these steps because it is not needed.
Thus, choice A is not a step in using paper folding to find the midpoint of a line segment.
Using the given equation y-3 = 3/4(x+2)
Give Y a value and then solve for x:
If y = 0 the equation is now:
0 -3 = 3/4(x+2)
Solve for x:
-3 = 3/4x + 1.5
-4.5 = 3/4x
x = -4.5 / 3/4
x = -6
So the first point would be (-6,0)
Now make x 0 and solve for y:
y -3 = 3/4(0+2)
y-3 = 0 + 1.5
y = 4.5
So the 2nd point would be (0,4.5)
You are close, but the dot you have on y=4, needs to be moved up to 4.5.
Answer:
C. X = 10.247
Step-by-step explanation:
X -4.21 = 6.047
just you will add 4.21 to both sides of the equation
X -4.21 + 4.21 = 6.047 + 4.21
X = 10.247
