The mathematical expression that Katherine requires to know the price of the objects that she is going to buy is 8 * ($20.75) + 120 * ($5/12) = $216
<h3>How to write an expression for this procedure?</h3>
To find a mathematical expression for this procedure we must take into account the values that we know.
For example, we know that it requires 15 pansies for each tree. This can be expressed like this:
On the other hand, we must calculate the price of each tree and the pansies that are going to be used to surround each one as shown below.
- Cost of trees = 8 * $20.75
- Pansies Cost = 15 * ($5/12)
According to the above, the final expression, in which all the necessary data for Katherine is included, is:
- 8 * ($20.75) + 120 * ($5/12) = $216

Answer:

Step-by-step explanation:
In probability, "OR" means "+" and "AND" means "*".
The total amount of people is:
32 + 54 + 78 + 112 + 96 = 372
Number of diabetic patients are 54
Number of eye patients are 112
Since we want "OR", we will add the two probabilities:
P(diabetic or eye problem) = 54/372 + 112/372 = 83/186
Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2
