What is the value of x?
Olegator [25]

Answer:

48

Step-by-step explanation:

On either side of a line, there is an angle of 180.  This means that when two lines intersect, the angles on either side will equal 180.

To solve this problem, add the two angles and set it equal to zero.

(x + 34) + (2x + 2) = 180

x + 34 + 2x + 2 = 180

3x + 36 = 180

3x = 144

x = 48

The value of x is 48.

X/(x-2) + (x-1)/(x+1) = -1 <br><br> How to solve?
kirill115 [55]
Multiply entire equation by (x-2)(x+1) to get rid of the denominators That would lead to X(x+1)+(x-1)(x-2)=-1(x-2)(x+1)
Finally, using distributive property and foil, you would get x^2+x+x^2-3x+2=(-x^2+x+2).2x^2-2x+2=-x^2+x+23x^2-3x=0
3x(x-1)x=0 and x=1

mixer [17]
 30%÷100% = 0.30; $85×0.30= $25.50; 85 - 25.50= $59.50.
 15%÷100% = 0.15; $59.5 ×0.15 =8.92; 59.50 - 8.92= $50.58
$50.58
