What it wants you to do is to put it into a form where on the one side of the equation there is y and nothing else. for this, we need to get rid of the 0.9.
how do we do that?
we divide both sides of the equation by 0.9:
6.3/0.9=y
that's ugly, right? but if both denominator and nominator are decimal fractions of the same sort; we can multiply both by 10 and get rid of the point:
63/09=y
and...

so basically 7=y, or y=7
and this is the solution!
Just show how you dived the equation and found the X
Answer:
B
Step-by-step explanation:
Edge
Answer:
120
Step-by-step explanation:
Since the figures are similar the angles are the same
<A = <F
<B = <E
<C = <C
<D = <G
We know <G = 120 so angle D = 120
W = <D = 120
