X+ 3y = 1 -----(first equation)
-2x+7 = -23 ---(second equation)
-2x = -23-7
x = 30/2
x = 15

Now, Substitute the value of x in first equation,
15 + 3y = 1
3y = 1 - 15
y = -14/3

In short, Final Answers are: x = 15 & y = -14/3

Hope this helps!

Lisa is in charge of planning a reception for 3600 people. She is trying to decide which snacks to buy. She has asked a random s

Olenka [21]

Answer:

The expected number of the people at the reception whose favorite snack will be chips is 1152

Step-by-step explanation:

Given

The data in the above table and

Reception = 3600

Required

Predict the number of the people at the reception whose favorite snack will be chips.

The first step is to determine the total number of samples;

$Total = Brownies + Cookies + Chips + Other$

$Total = 32 + 22 + 56 + 65$

$Total = 175$

The next step is to determine the fraction of people whose favorite is chips

$Fraction = \frac{Chips}{Total}$

$Fraction = \frac{56}{175}$

The product of the above fraction and the expected number of people in the reception is the solution to this question;

$Expected\ Number = \frac{56}{175} * 3600$

$Expected\ Number = \frac{56* 3600}{175}$

$Expected\ Number = \frac{201600}{175}$

$Expected\ Number = 1152$

Hence, the expected number of the people at the reception whose favorite snack will be chips is 1152
