C=Candy Bar(s)

D=Drink(s)

--------------------

60C+110D=265

120C+90D=270

-------------------

Therefore:

60C=265-110D

Therefore:

2(60C)+90D=270

2(265-110D)+90D=270

530-220D+90D=270

530-270=220D-90D

260=130D

D=260/130

D=2

-------------------

If D=2,

60C=265-110(2)

60C=265-220

60C=45

C=45/60

C=3/4

C=0.75

---------------------

<em>*Candy bars sell for $0.75 whilst drinks sell for $2.00.</em>

Solve the equation: 5/6 = 1/3 + D
Sauron [17]
Answer: \frac{1}{2} 
 
Explanation:
\frac{5}{6} =  \frac{1}{3}  + D 
\frac{5}{6}  -  \frac{1}{3} = \frac{1}{3}  -  \frac{1}{3} + D 
\frac{5}{6} -  \frac{1}{3} = D 
\frac{5}{6} - 2(\frac{1}{3}) = D
\frac{5}{6} - \frac{2}{6} = D 
\frac{3}{6} = D = \frac{1}{2}
