Answer:
x = -9
Step-by-step explanation:
First, divide both sides by 12 to isolate the expression, x + 11
12(x + 11)/12 = 24/12
x + 11 = 2
Then, subtract 11 from both sides
x + 11 = 2
- 11 - 11
x = -9

Answer:
1
Step-by-step explanation:
Given the system of equations below
y=2x+5
y=x+6
Equating the right hand side of the expressions we will have;
2x+5 = x+6
Collect the like terms;
2x - x = 6 - 5
x = 1
Hence the x-coordinate of the solution to the system is 1
Answer:
20
Step-by-step explanation:
interior angle + exterior angle = 180°
162° + exterior angle = 180° ( subtract 162° from both sides )
exterior angle = 18°
the sum of the exterior angles of a polygon = 360° , then
number of sides = 360° ÷ 18° = 20
