Answer:
for 18 x is 6 and for 20 it is 11
Step-by-step explanation:
For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6
For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11
Hope this helps :)
Answer:
18.) x = 6
20.) x = 11
Step-by-step explanation:
<em><u>18.)</u></em>
We know that line segments FC and ED are parallel to each other so they are congruent to each other:
-1 + 2x = 5 + x
-1 + x = 5
<u>x = 6</u>
<u><em>20.)</em></u>
We know that line segments DE and CF are parallel to each other so they are congruent to each other:
18 = -4 + 2x
22 = 2x
22/2 = x
<u>11 = x</u>
Hope this helps!
