An expression which is represented by the diagram (see attachment) is: A. -6 - (-1).
<h3>What is an expression?</h3>
An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.
By critically observing the diagram (see attachment), we can logically deduce the following information:
- There are a total of 6 negative tiles.
- Among the 6 negative tiles, 1 tile is crossed out.
In this context, we can the diagram (see attachment) by using the following expression:
-6 - (-1)

First find one third of the number 72. We can do this by either dividing 72 by 3, or by multiplying 72 by 1/3. I will divide 72 by 3.
72/3 = 24
We have completed half of the problem; one third of the number 72. Now the number Barbie is thinking of is twenty less than the number we just found, 24.
To solve this problem subtract 20 from one third of the number 72; 24.
24 - 20 = 4
The number that Barbie is thinking of is 4.

That answer in your list should say 64.00 * PI ft^2
162 * .80 = 129.6. so roughly 130 animals are going to be aquatic plants. So, 162-130 equals 32. 32 animals
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x
