Step-by-step explanation:
First plot the x and y on graph,
at (4,2)
The slope is -2/3
slope= rise/run, negative menas graph up to the left
go along the x axis 3 units left from (4,2) then travel upwards 2 units
Answer:
<em>4.42 ounces </em>
Step-by-step explanation:
Given:
The solid food Stacie has eaten in the noon meal:
1. 
of a 3-ounce serving of meatloaf.
2. 
of her 3-ounce serving of mashed potatoes
3. 
of a 2-ounce serving of green beans
To find:
How many ounces of solid food was consumed by Stacie (upto 2 decimal places) ?
Solution:
Let us convert the given fractions to decimal form upto 2 decimal places:
1. 
meatloaf .
2. 
mashed potatoes .
3. 
green beans.
Let us add the above 3 quantities to get total solid food consumed.
Total solid food consumed = 1.50 + 2.25 +0.67 = <em>4.42 ounces.</em>

So, the answer is <em>4.42 ounces.</em>
Answer:
<em>$4.15</em>
Step-by-step explanation:
Let the cost of a cheeseburger be x
Let the cost of a soft pretzels be y
If Mr. Smith goes to the concession stand and buys 2 soft pretzels and 1 cheeseburger for $8.25, this is expressed as;
x + 2y = 8.25 .... 1
Also, if Mr. Martin goes to the same concession stand and buys 1 soft pretzel and 3 cheeseburgers for $13.50, this is expressed as;
3x + y = 13. 50..... 2
The required equations are:
x + 2y = 8.25
3x + y = 13. 50
Find x and y by solving simultaneously:
From 1: x + 2y = 8.25
x = 8.25 - 2y ..... 3
Substitute 3 into 2
3(8.25-2y)+y = 13.50
24.75 - 6y+y = 13.50
24.75 - 5y = 13.50
-5y = 14.50 - 24.75
-5 y = 10.25
y = -10.25/-5
y = 2.05
Since x = 8.25 - 2y
x = 8.25 - 2(2.05)
x = 8.25 - 4.1
x = 4.15
<em>Hence the cost of a cheesburger is $4.15</em>
