Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to call the numbers x and y.
A number is equal to twice a smaller number plus 3.
Greater number is x, and smaller is y. So
The same number is equal to twice the sum of the smaller number and 1.
This means that
Equaling the values for x:
Since division by 0 does not exist, it means that there is no solution for the system.
Answer:
a. $18.36 for 3 pizzas : k = 6.12
b. $4.17 for 3 pounds of bananas . k = 1.39
c. $16.48 for 4 pounds of potatoes . k = 4.12
d. 2 cups of flour to make 24 cookie . k = 2
Step-by-step explanation:
<u>PROPORTIONALITY:</u>
Two quantities x and y are said to proportional to each other
if for x ∝ y , x = y k.
Here, k i s called the PROPORTIONALITY CONSTANT.
⇒
Now, for the given quantities:
a. $18.36 for 3 pizzas [box]
Here,
So, the proportionality constant is 6.12.
b. $4.17 for 3 pounds of bananas [box]
Here,
So, the proportionality constant is 1.39.
c. $16.48 for 4 pounds of potatoes [box]
Here,
So, the proportionality constant is 4.12.
d. 2 cups of flour to make 24 cookies
Here,
So, the proportionality constant is 12
