X=price of a hot dogy=price of a soft drinkWe can suggest the following system of equations:
6x+4y=133x+4y=8.50
We solve this system of equations by reduction method.  6x+4y=13-(3x+4y=8.5)------------------------   3x=4.5              ⇒x=4.5/3=1.5
Answer: the price of a hot dog will be $1.5.

If you want to know the price of a soft drink, you have to find "y".6x+4y=13
6(1.5)+4y=139+4y=134y=13-94y=4y=4/4y=1
The price of a soft drink is $1. 
Hope this helps! :)

An amusement park's owners are considering extending the weeks of the year that it is opened. The owners would like to survey 10

The best way to randomly choose the 100 families would be to allow a random number generator to come up with 100 families within a 50 radius of the amusement park.

Using this method would ensure that it is more randomised & not limited to people who come at a specific time or are in a specific area as well as it not be affected by subconscious bias of people when selecting people to survey.

Determine the equation
sergejj [24]

Answer:

y=\frac{3}{4} x-\frac{5}{4}

Step-by-step explanation:

two points on the line are

(-1, -2)

(-5, -5)

The slope:

m=\frac{-2-(-5)}{-1-(-5)} =\frac{-2+5}{-1+5} =\frac{3}{4}

The equation:

with (-1,-2)

y-(-2)=\frac{3}{4} (x-(-1))

y+2=\frac{3}{4} x+\frac{3}{4}

y=\frac{3}{4} x+\frac{3}{4} -\frac{8}{4}

y=\frac{3}{4} x-\frac{5}{4}

Hope this helps

PLS ANSWER I WILL GIVE YOU BRAINLIST AND A THANK YOU!!
Arte-miy333 [17]

Answer:

x=45

Step-by-step explanation:

2x+45+x=180

Combine 2x and x to get 3x.

3x+45=180

Subtract 45 from both sides.

3x=180−45

Subtract 45 from 180 to get 135.

3x=135

Divide both sides by 3.

x=135/3

Divide 135 by 3

x=45
