koban [17]

Answer:

46%  of Xander's friends prefer to stay home on Friday nights.

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

\frac{23}{50}\ of\ Zanders\ friends\ prefer\ to\ stay\ home\ on\ Friday\ night.

i.e

Zanders friends prefer to stay home on Friday night = 23

Total numbers of Zanders friends are 50.

Part value = 23

Total value = 50

Put in the formula

Percentage = \frac{23\times 100}{50}

Percentage = \frac{2300}{50}

Percentage = 46%

Therefore 46%  of Xander's friends prefer to stay home on Friday nights.

Options are:<br><br> X=2, y=3<br><br> X=3, y=2<br><br> X= -2, y=3<br><br> X=4, y=8
trapecia [35]

Step-by-step explanation:

2x - 5 = y - 5

2x = y

x = y/2

y - 3 = x + 1

Substitute the value of x here,

y - 3 = \rm{\dfrac{y}{2} + 1}

y - 3 = \rm{\dfrac{y + 2}{2}}

2y - 6 = y + 2

y = 8

Now, x = 8/2

x = 4

So, go for D part, it is the correct answer.
