6) mcpof x + 42, mcpor - 87°,
and mzfor r + 65. find x.

  x =  -10 .

Explanation:

         x + 42 + x + 65  = 87 ;  Solve for "x" ; 

           2x + 107 = 87 .
 
Subtract "107" from each side of the equation:

           2x + 107 − 107 = 87 − 107 ;

             2x = -20 ;

Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;

             2x / 2  =  -20/2 ;

                 x = -10 .

Answer: b 2 = 1.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

therefore, b 2= 1.
