2.5 (6 - 2x) + 11 = 104 - 1.5 (6x + 12)
Distribute both sides
15 - 5x + 11 = 104 - 9x - 18
Combine liked terms
26 - 5x = 86 - 9x
-26 on both sides
-5x = 60 - 9x
+9x on both sides
4x = 60
/4 on both sides
x = 15

1. What is the approximate solution of the linear system represented by the graph below?
nlexa [21]

Answer:

x = 5 and y = 6; that is the (5, 6) (x, y) pair.

Step-by-step explanation:

The graph shows two lines that cross at the point (5, 6) on the plane (see attached image).

This means that the point x=5 and y=6 belongs to both lines (is a solution for both equations representing the lines) and therefore this pair of values is the solution to both equations in the system.

Use the drop-down menus to choose steps in order to correctly solve 5(z + 6) – 2 = 9z for z.
shusha [124]
Solve for z:
5 (z + 6) - 2 = 9 z

5 (z + 6) = 5 z + 30:
5 z + 30 - 2 = 9 z

Add like terms. 30 - 2 = 28:
5 z + 28 = 9 z

Subtract 9 z from both sides:
(5 z - 9 z) + 28 = 9 z - 9 z

5 z - 9 z = -4 z:
-4 z + 28 = 9 z - 9 z

9 z - 9 z = 0:
28 - 4 z = 0

Subtract 28 from both sides:
(28 - 28) - 4 z = -28

28 - 28 = 0:
-4 z = -28

Divide both sides of -4 z = -28 by -4:
(-4 z)/(-4) = (-28)/(-4)

(-4)/(-4) = 1:
z = (-28)/(-4)

The gcd of 28 and -4 is 4, so (-28)/(-4) = (-(4×7))/(4 (-1)) = 4/4×(-7)/(-1) = (-7)/(-1):
z = (-7)/(-1)

(-7)/(-1) = (-1)/(-1)×7 = 7:
Answer:  z = 7

Find “X” thank you!!!! <33
xxTIMURxx [149]

Answer:

Step-by-step explanation:

If we assume that the angle at A is 90 degrees.. which it does seem like it would be.  then use that the sum of the angles around the inside of a right triagle is 180 .   so  you have

180 = 37 + 90 + x

53° = x  

does that help?
