Answer:
n = 36
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , that is
AB = DC , substitute values
n - 5 =
n + 7 ( multiply through by 3 to clear the fractions )
2n - 15 = n + 21 ( subtract n from both sides )
n - 15 = 21 ( add 15 to both sides )
n = 36
Answer:
The graph in the attached figure
see the explanation
Step-by-step explanation:
Let
x -----> the number of bottles
y ----> the total cost of the water
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
This problem represent a direct (proportional) variation
so
For x=1, y=$1.50
----->
The linear equation is equal to
<u><em>Find the ordered pairs</em></u>
First
(1,1.50)
Second
For x=2
Find the value of y
Substitute in the equation
y=1.50(2)=3
The point is (2,3.00)
Third
For x=3
Find the value of y
Substitute in the equation
y=1.50(3)=4.50
The point is (3,4.50)
Fourth
For x=4
Find the value of y
Substitute in the equation
y=1.50(4)=6.00
The point is (4,6.00)
The four ordered pairs are
(1,1.50), (2,3.00),(3,4.50) and (4,6.00)
using a graphing tool
plot the points
