110 = 5x + 3y (yet x + y = 30)
Therefore the only explanation would 10 kids bought lunch and 20 packed because....
10 + 20 = 30 AND 5 * 10 = 50 3 * 20 = 60 60 + 50 = 110

Answer:
19 14/5
Step-by-step explanation:
4 1/3 x 4 3/5
13/3 x 23/5
299/15 = 19 14/5
white : milk : dark
w : m : d
The ratio of white to not white is 3:4
w : (m+d) = 3:4
The ratio of not dark to dark is 17:4.
(w+m) : d = 17:4
---------
We treat the colons as fraction bars and cross multiply.
4w = 3(m+d) = 3m + 3d
4w + 4m = 17 d
Subtracting,
4m = 17d - (3m+3d) = 14d - 3m
7m = 14 d
m/d = 14/7
m:d = 2:1
Since w:(m+d)=3:4 let's make m+d a multiple of 4.
m:d = 8:4
w : (m+d) = 3:4 = 9:12
w:m:d = 9:8:4
Answer: 9:8:4
Check:
white to non white 9 to 8+4=12 = 3:4, good
non dark to dark (9+8):4=17:4, good
Proper fractions for 3(5/8) = 29/8.
<u>Step-by-step explanation:</u>
The given fraction can be converted into improper fraction as the numerator will be greater than the denominator.
3 is multiplied by 8 and then it is added to 5,
we will get 29,
and
3 (5/8) = ((3×8)+5)/8
= (24+5)/8
= 29/8
so finally 29/8 is the answer.
