Answer:
<h3>x = 7</h3>
Step-by-step explanation:
The sum of the adjacent side of the trapezium is 180 degrees, Hence;
97 - 3x + 69+5x = 180
166 + 2x = 180
2x = 180 - 166
2x = 14
x = 14/2
x = 7
Hence the value of x is 7
Answer:
answer for 8 is 1500
Step-by-step explanation:
Isolate the absolute value expression
0.07x+0.08 (9000-x)=700
Solve for x
0.07x+720-0.08x=700
0.07x-0.08x=700-720
-0.01x=-20
X=20÷0.01
X=2,000 invested at 7%
9000-2000=7000 invested at 8%
Answer:
Parallel lines
Step-by-step explanation:
Line BC:

Line AD:

Adding both equations, in this case, gives us the point at which the lines intersect:

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.
