   x = 36.2  .
______________________________________________

Explanation:
________________________________________________
2x - 1 + 3x = 180 ;

Combine the "like terms" on the left-hand side of the equation:
________________________________________________
   +2x  + 3x = + 5x ;
_____________________________________
 And rewrite:
_____________________________________
   5x - 1 = 180 ;
_____________________________________
  Add "1" to each side of the equation:
_____________________________________
   5x - 1 + 1 = 180 + 1 ;
_____________________________________
     5x = 181 ;  
_____________________________________
  Divide EACH SIDE of the equation by "5" ;
_____________________________________
     5x / 5 = 181 / 5 ;
_____________________________________
   to get:
_____________________________________
  x = 36.2  .

AlekseyPX
 surface area of the outside of a cube shaped closed-top water tank whose edge length is 7.2 ft, can be solved by solving the area of each face of a cube. since the cube has 6 faces and all the faces are congruent because it all has the same edge.
so the formulaA = 6s^2where s is the edge lengthA = 6 ( 7.2^2)A = 311.04 sq ft.

If the point (x, square root 3/2) is on the unit circle, what is x?
photoshop1234 [79]

Answer:

\frac{1}{2}

Step-by-step explanation:

On a unit circle, the only points where y = \frac{\sqrt{3} }{2} have an x coordinate of \frac{1}{2} or \frac{-1}{2} . Since only one of those is an option, the answer is \frac{1}{2}.
