Answer:
E. 31
Step-by-step explanation:
Add the values together.
4 (2/6) + 3 (3/6) + 2 (3/6) = 9 (8/6) or 10 (1/3)
multiply 10 by 3 to find how many thirds there are and add 1 to that number for the extra 1/3.
So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
Yes because the domain doesn't repeat its self
