Answer:

y = -2

Step-by-step explanation:

5 + y + 3

Isolate y

y = -2

elixir [45]

Answer:

Total number of correct answers = 54

\texttt{Fraction of the marks did he get correct}=\frac{\texttt{Total number of correct answers}}{\texttt{Total number of questions}}\\\\\texttt{Fraction of the marks did he get correct}=\frac{54}{66}\\\\\texttt{Fraction of the marks did he get correct}=\frac{9}{11}
