Solution:
we have been given an equation expressing a relationship in terms of one variable.
The equation is
or
we have been asked to asked to rewrite the equation in terms of a different variable, I.
Divide both the sides by R we get
23
(I think that’s what your asking)
You take 298 x .15 =44.7
298-44.7=253.3
We have the total length of VW and we know that C lies somewhere on that line.
Therefore:
VC + CW = VW
z+13+z+8 = 61
2z+21=61
2z=61-21
2z=40
z=40/2
z=20
