The difference between the given values as a whole number is 27
<h3>Finding the difference between values</h3>
To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value.
Given the following expression
44 - 17
This can also be expressed as
44 = 40 + 4
17 = 10 + 7
Substitute
44 - 17 = (40 + 4) - (10+ 7)
Expand
44 - 17 = 40 + 4 -10 - 7
44 - 17 = 40 - 10 + 4 - 7
44 - 17 = 30 - 3
44 - 17 = 27
Hence the difference between the given values as a whole number is 27

The proportionality constant of the given graph is k = 16.
<h3>How to find the proportionality constant of a graph?</h3>
The proportionality constant of a graph is the ratio of the y-coordinates to the x-coordinates.
Thus, it is written as k = y1/x1 = x2/y2 = ... = yn/xn
<h3>Calculation:</h3>
The given graph has the coordinates as
x = 0; y = 0 i.e., (0, 0)
x = 0.5; y = 8 i.e., (0.5, 8)
x = 1; y = 16 i.e., (1, 16)
x = 1.5; y = 24 i.e., (1.5, 24)
and so on.
Then, the ratio of y - coordinate to the x - coordinate is
k = 8/0.5 = 16
or
k = 16/1 = 16
or
k = 24/1.5 = 16
and so on.
So, the proportionality constant for the given graph is k = 16.

Answer:
t = 1
Step-by-step explanation:
16 - 2t = 5t + 9
+2t +2t
-------------------------
16 = 7t + 9
-9 -9
--------------------------
7 = 7t
/7 /7
--------------------------
1 = t
Answer:
The second choice
Step-by-step explanation:
Perimeter is calculated by adding the length and width but multiplied by 2. You add 3.2 and 1.5 and get 4.7. Multiply 4.7 by 2 would give you 9.4.
Area is multiplying the length and width. 3.2 multiplied by 1.5 would be 4.8
