The sum of a number and its reciprocal is 2whole number 1 over 6. Find that number​
notsponge [240]

Answer:

  2/3 or 3/2

Step-by-step explanation:

Let x represent the number. The given relation is ...

  x +1/x = 2 1/6

  x^2 +1 = (13/6)x

  6x^2 -13x +6 = 0 . . . . . subtract the right side and multiply by 6

  (6x -9)(6x -4)/6 = 0 . . . . factor

  (2x -3)(3x -2) = 0 . . . . . . simplify a bit

  x = 3/2  or  2/3 . . . . . . . . values of x that make the factors zero

The number is 2/3 or its reciprocal, 3/2.

State if the pair of triangles are similar. If so, state how you know they are similar and
RideAnS [48]
They can’t be similar. Similar triangles have congruent corresponding angles, and two angles are given on each. Neither of those correspond to another on the opposite triangle. Basically, there’s no way to have three congruent angles, so they aren’t similar.

What is the value of x in <br> 150-35x=45
Annette [7]
Your answer is x = 3 because if you take 150 and subtract it by both sides: 
 150 - 35x = 45
-150           -150

you have to cross out both 150 and -150, take 45 and subtract 150 which will give you -105. 
  -35x = -105 

take -35 and divide by both sides. Cross out the two -35's. Take -105/-35 which your answer is x = 3. Hopes this helps. :)
