When we say number sense, this refers to someone who clearly understands the meaning of numbers and its relationships. Meaning, he can easily perform mathematical activities and even apply this in real life. Therefore, the answer to the question above is option D.
The first few twin prime pairs are : (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43), (59, 61), (71, 73), (101, 103), (107, 109), (137, 139), …etc. FACT : There are 409 Twin

We can use the law of sines to solve this...
sin30 / 4.38 = sin2 / y (multiply both sides by y)
ysin30 / 4.38 = sin2 (multiply both sides by 4.38)
ysin30 = 4.38sin2 (divide both sides by sin30)
y = 4.38sin2 / sin30
y = .305719 (change to degrees)
y = 18°
Well use the distributive property
-98=4x-2(5x+13)
Now multiply 2 times 5x+13
-98=4x-10x-26
Now combine like terms
-98=-6x-26
Now get 26 on the other side by adding it to -98
-6x=-72
x=12
