Answer:
D is the answer. There are 5 boxes, that each has 3 filled in.
3:5=x:50
Therefore 5 ×x = 50
x = 10
Therefore 3 × 10 = 30
therefore 30 blue pens
proof = 30 blue + 50 red= 3+ 5
therefore 80 = 8x
It would be 9 1/3 divided by 7/1 or 28/3 * 1/7
It would give you 28/21 which would simplify to 4/3 and still leave you with an improper fraction
3 is less than or equal to x-9 is less than or equal to.
3<= x-9<=8
<= these mean less than or equal to.
