X-9= 1/4x + (1/4x + 12) + (1/4x - 3) what’s that answer?

Mathematics

Answer:

x = 72

Step-by-step explanation:

Make the problem simpler by eliminating the fractional coefficients:

x-9= 1/4x + (1/4x + 12) + (1/4x - 3), when multiplied by 4, becomes:

4x - 36 = x + x + 48 + x - 12

Summing up all the x terms, we get:

4x - 2x - x = 48 - 12 + 36

Then x = 72

7/12-9/8(2x-1)-5/6(3x+2)
butalik [34]
7/12-9/8(2x-1)-5/6(3x+2)=0
(7*2-9(2x-1)*3-5(3x+2)*4)/24=0
(14-9(2x-1)*3-5(3x+2)*4)/24=0
(14-27(2x-1)-20(3x+2)/24=0
(14-54x+27-60x-40)/24=0
(14+(-54x-60x)+27-40)/24=0
(14-114x+27-40)/24
(-144x+1)/24=0
-114x+1=0
-114x=-1
x=1/144

Answer: b. The adjacent angles formed by two intersecting lines are supplementary.


Step-by-step explanation:

In the given picture , we can see that there are intersecting lines with adjacent angles which have shown.

If we add the adjacent angles for each pair of intersecting lines we get,

135^{\circ}+45^{\circ}=180^{\circ}

130^{\circ}+50^{\circ}=180^{\circ}

160^{\circ}+20^{\circ}=180^{\circ}

Therefore,b is the right option "The adjacent angles formed by two intersecting lines are supplementary."

  • Two Angles are supplementary when their sum is 180 degrees.
  • Two Angles are complementary when their sum is 90 degrees.
  • Vertical angles are always equal.
