Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
Answer:
Depends. But I think B, One solution most of the time. Not sure if that is correct though.

Multiples of 6:
6, 12, 18, 24, <u>30</u>, 36, 42, 48, 54, 60, ...
Multiples of 10:
10, 20, <u>30</u>, 40, 50, 60, ...
X is greater than or equal to 15
19 ft.
Pytahgorean theorm. A^2 + B ^2 = C^2
49 + 100 = 149
Square root the 149, which is ~12
That means the hypotenuse is twelve feet, and with the base of the pole being seven, the pole was originally 19 feet tall.
