Tamiku [17]

Answer: 40

Step-by-step explanation:

Number of DVDs = 160

Thrillers = 35%

Comedies = 2/5 = 40%

Science fiction = 100 - (35 + 40) = 100 - 75 = 25%

The number of science fiction DVDs that Rani has will be:

= 25% × 160

= 25/100 × 160

= 40

(2x+2y=10)+(-x+y=1)

ruslelena [56]

$\bf \begin{cases}
2x+2y=10\\
-x+y=1
\end{cases}\\\\
-------------------------------\\\\
-x+y=1\implies y=1+x\impliedby \textit{let's plug that in the first equation}
\\\\\\
2x+2(\stackrel{y}{1+x})=10\implies 2x+2+2x=10\implies 4x=8
\\\\\\
x=\cfrac{8}{4}\implies \boxed{x=2}\impliedby \textit{let's plug that in the second one}
\\\\\\
-(\stackrel{x}{2})+y=1\implies \boxed{y=3}$
