Answer:
x = 20
Step-by-step explanation:
To solve this, your goal should be to get x by itself in front of the equal sign. To do this, first add 12 to both sides of the equal sign. This gets rid of the -12 since -12 + 12 = 0.
3x - 12 + 12 = 48 + 12
3x = 60
The last step is to divide 3 from both sides.
3x / 3 = x.
60 / 3 = 20.
This leaves you with x = 20 which is the answer.

Answer:
1
Step-by-step explanation
Since you are given two points you can calculate the slope by use the formula Y1-Y2/X1-X2.
In this case:
Y1 = 5
Y2 = 7
X1 = 7
X2 = 9
(5-7)/(7-9) = -2/-2 = 1
Answer:
x = 21º
Step-by-step explanation:
∆ ABC is isosceles therefor
Angles B and C are congruent
(180 - 18)/2 = 162/2 = 81º
------------------
∆ BCD is equilateral therefor all angles are 60º
---------------------------
x = = 81 - 60
x = 21º
