Let's add the fractions first and then we can estimate the sum.

= 31/4 + 17/3 + 8/18
change to common denominators

= 279/36 + 204/36 + 16/36
add numerators only

= 499/36 or 13 31/36 or 13.86

ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.

WELL, THIS IT HOW I GOT Y = 14
50 = 2X
25=X

then ; 50 + 2(25) + (5y+10) = 180
50 + 50 + 5y+10 =180
110 + 5y =180
5y = 180 -110
5y = 70
y = 14
