Answer:
2.80
Step-by-step explanation:
Take the cost and divide by the number of padlocks
25.20/9
2.80
Each padlock costs 2.80
Answer:
$2.80
Step-by-step explanation:
25.20 is the total price, and there are 9 padlocks, so to get the price of each padlock, divide 25.20 by 9
25.20/9=2.8
write your answer in dollars: $2.80
Answer:
when a number is divisible by 9, then the number is divisible by 3.
Step-by-step explanation:
They tell us "When a number is divisible by 9, the number is divisible by 3" we could change it by:
when a number is divisible by 9, then the number is divisible by 3.
Which makes sense because the number 9 is a multiple of the number 3, which means that the 9 can be divided by 3, therefore, if the number can be divided by 9, in the same way it can be divided by 3 .
The statement "When a number is divisible by 9, the number is divisible by 3" can be rewritten in if-then form as: If a number is divisible by 9, then the number is divisible by 3.
In this case, the conclusion is that the number is divisible by 3.
Here is a table that summarizes the if-then form of the statement:
| Hypothesis | Conclusion |
|---|---|---|
| A number is divisible by 9 | The number is divisible by 3 |
In other words, if the hypothesis is true (i.e., the number is divisible by 9), then the conclusion must also be true (i.e., the number is divisible by 3).
Here is an example:
Hypothesis: The number 18 is divisible by 9.
Conclusion: The number 18 is divisible by 3.
Both the hypothesis and the conclusion are true, so the if-then statement is true.

Answer:
x² +y² -6x -16y +48 = 0
Step-by-step explanation:
Given:
Find:
general form equation for the circle
Solution;
The standard form equation for the circle is ...
(x -h)² +(y -k)² = r² . . . . . circle with radius r centered at (h, k)
(x -3)² +(y -8)² = 5²
Subtracting 25 and expanding this will give the general form.
x² -6x +9 +y² -16y +64 -25 = 0
x² +y² -6x -16y +48 = 0
_____
Additional comment
"General form" of an equation is usually the form f(x,y) = 0, where f(x, y) is written in "standard form," with terms in lexicographical order and decreasing degree.
