Answer:

x = 4

Step-by-step explanation:

9(x - 2) = 18

9 * x = 9x

9 * -2 = -18

9x - 18 = 18

+18         +18

9x - 18 + 18 = 9x

18 + 18 = 36

9x = 36

----   -----

9      9

9x/9 = x

36/9 = 4

x = 4

ANSWER ASAP |What is the measure of angle x?
Marina86 [1]

Answer:

x = 83°

Step-by-step explanation:

41, 56 and the missing angle = 180° ( form a straight angle )

missing angle = 180° - (41 + 56)° = 180° - 97° = 83°

The angle x and the missing angle are vertically opposite and congruent

Hence x = 83°

What is the solution of the matrix equation?
katrin [286]

Hello from MrBillDoesMath!

Answer:

The first choice ( -12, 20)



Discussion:

Using matrix multiplication we find the equations:


1x  + 1y = 8                     (A)

2x  + 3y = 36                   (B)


Next, compute

  2(A) - B  =>

         (2x + 2y) - (2x + 3y) = 2*8 - 36    =>

          (2x - 2x) + ( 2y-3y) = 16 - 36 =>

          -y = -20  =>

         y = 20


Substituting this y value in (A) gives

         x + 20 = 8 =>

         x = 8 - 20 =>

        x = -12


The answer is the first choice ( -12, 20)


Thank you,

MrB
