3 x + 9 = 44 - 2 x
subtract 9 from both sides:
3 x + 9 - 9 = 44 - 2x - 9
3 x = -2 x +35
Add 2 x to both sides:
3 x + 2 x = -2 x + 35 + 2 x
5 x = 35
Divide both sides by 5 :
5x / 5 = 35/ 5
x = 7
hope this helps!
I am attaching the full question...
Because AB is parallel to CD, the transversal line EF creates the same angles in AB and CD.
This means that 3x+40 = 4x
..........==>> x = 40 degrees
Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 252π = π*r^2*7
.. (252π)/(7π) = r^2
.. 36 = r^2
.. 6 = r
The radius is 6 cm. Selection D is appropriate.
