Answer:
5.25 + 2.50 = 7.75. 10 - 7.75 =2.25
Step-by-step explanation:
Answer:
Odd numbers.
Step-by-step explanation:
Closed under addition means you will able to take any two numbers from whatever set is mentioned and add them to get a number in that same set.
(If I say counting numbers, I'm still talking about the natural numbers.)
So let's look at the natural numbers {1,2,3,4,5,6,...}.
1+1=2
1+2=3
1+3=4
...
6+19=25
Let a and b be counting numbers.
a+b is still going to be a counting number.
You will always get a counting number when adding two counting numbers. So the counting numbers (also known as the natural numbers) is closed under addition.
Let's skip down to odd numbers because the other sets are similar to the first.
Let's add a pair of odd numbers.
3+5=8
8 is not odd so the odd numbers are not closed under addition because we will not always get an odd number. In fact, you will never get a odd number, but the thing is you just need one example to show it is not closed.
(2k+1)+(2a+1)
2(k+a)+2
2(k+a+1) is even so adding two odds will always give you an even.
The equation for the cartesian form of representation of a plane is given by ax + by + cz = d.
<h3>What is the cartesian form?</h3>
The cartesian form is a mathematical model which is used for the graphical representation of either a point, line, or plane in a two-dimensional (2D) or three-dimensional (3D) plane.
Mathematically, the cartesian form of representation of a plane is given by this equation:
ax + by + cz = d.
<u>Where:</u>
- a, b, c are the direction on each axis.
- d is the distance from the origin.

Answer:
because an integer divided by an integer is equal to integer and the answer isn't up to one so it is zero
