Answer:
x = 11
Step-by-step explanation:
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
then 6/(6 + 48) = 5/(5 + 3x + 7)
6(3x + 12) = 5(54)
18x + 72 = 270
18x = 198
x = 11
A ratio has to be equal to what is given, in this case, 5/45. 5 divided by 5 is 1 and 45 divided by 5 is 9. So one answer is 1/9.
Answer: [A]: "library card".
____________________________________
Explanation: One would need a valid, government-issued photo ID card (i.e. that has not expires).
Although SOME library cards include one's picture, library cards do not constitute "valid ID's" because they are not "government-issued" and would, theoretically, be easy to be made fraudulently (e.g. not have security-issued seals and features).
Even "school ID's"; or "college ID cards"; even if "current" (e.g. currently enrolled" with a photo ID) would not be considered "official" and would only be considered "secondary ID".
