Help, with solving rational equations! I am no good at it :( Solve for x: 2 over 5 plus 3 over 5 x equals quantity x plus 5 over
mamaluj [8]
If this is your equation: \frac{2}{5} + \frac{3}{5x} = \frac{x+5}{10}
Solution:
LCD for 5 and 5x is 5x
\frac{x}{x} ( \frac{2}{5} )+ \frac{3}{5x} = \frac{x+5}{10}
\frac{2x}{5x} + \frac{3}{5x} = \frac{x+5}{10}
\frac{2x+3}{5x} = \frac{x+5}{10}
10(2x+3)=5x(x+5) ←cross product
20x + 30 = 5x² + 25x  ←simplify with distributive property
0 = 5x² + 5x - 30 ←use inverse operations to collect all terms on one side
0 = x² + x - 6  ←if possible divide by numerical GCF (This case 5)
0 = (x + 3)(x - 2) ←Factor
x = -3 or x = 2
Please check by substitution in original equation... Both work

How do I do this ? I have 120 degrees but I need to solve for x
Darina [25.2K]
Since the legs are the same length, we know that the remaining two angles must be the same.

120+2x=180
2x=60
x=30

Final answer: x=30 degrees

Which expression finds the measure of an angle that is coterminal with a 126° angle?
N76 [4]
The expression that gives an angle that is coterminal with 126 is 126 + 720n. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression will give an angle which when it is drawn the terminal sides are on the same location with the 126 angle.
