Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
35-18=17
The most side dishes that they could get is 5
5*3=15
15+17=33
Answer:
Step-by-step explanation:
let their ages be x,y,z and x>y>z
x+y+z=74 ...(1)
x=(y+z)-12
or x-y-z=-12 ...(2)
y=z+5 ...(3)
add (1) and (2)
2x=62
x=62/2=31
from (1)
31+y+z=74
y+z=74-31=43
substitute from (3)
z+5+z=43
2z=43-5=38
z=38/2=19
y=19+5=24
so their ages are 31,24 and 19
