Based on the information given, the speed is 20 miles per hour.
From the information given, the winner of the local triathlon swam 0.5 miles, biked 15 miles and ran 2.5 miles and he finished the race in 54 minutes.
Note that 54 minutes = 0.9 hour.
The speed will be:
= (0.5 + 15 + 2.5) / 0.9
= 18/0.9
= 20 miles per hour.

Answer:
Your answer would be
- 2/25 x^3a^3
Or vice versa with the variables
- 2/25 a^3x^3
TO solve it’s pretty simple if you do it correctly.
So with all the variables in the two multiples, you can find a way to combine them
So ignoring everything else you’d get
a^2x * x^2a
You we can see the difference,
theres a^2 and a
Whilst there is also x^2 and x
Now we can combine them
a^3 x^3
Now we can do the normal multipacation with the fraction
2/5 * - 1/5 which is -2/25
Now combine
ANd you got it :D
Answer:
- Disitributive property.
- Addition property of equality.
Step-by-step explanation:
The complete exercise is attached.
For this exercise you need to remember the following properties:
1. The Distributive property states that:
2. The Addition property of equality states that:
Then, given the equation:
You can identify that the first property John used was the Distributive property:
After combining like terms, you can identify that the next property he applied was the Addition property of equality, adding 
to both sides of the equation:
The intersection of altitudes traced perpendicularly from a triangle's vertices to its opposite sides is known as an orthocenter.
Given that,
We have to find what is orthocenter.
We know that
<h3>What is Orthocenter?</h3>
The intersection of altitudes traced perpendicularly from a triangle's vertices to its opposite sides is known as an orthocenter. It is the location in a triangle where the three angles of the triangle intersect. An orthocenter's three primary characteristics are as follows:
Triangle: A three-sided polygon with three edges.
A triangle's height is the line that runs between its vertices and perpendicular to the other side. A triangle can therefore have three heights, one from each vertices.
Vertex - A vertex is the intersection of two or more lines.

Answer:
Infinite solutions or all real numbers
Step-by-step explanation:
divide the bottom equation by 2 then....
-3x +1/3 (9x + 36) = 12
-3x + 3x + 12 = 12 (distribute the 1/3 to the terms in the parentheses)
12 = 12
Infinite solutions
