The correct answer is A. A whole number
Explanation:
In mathematics, whole numbers include numbers that do not include a fraction, for example, the number 4.2 includes a fraction, and therefore it is not a whole number. Moreover, whole numbers include numbers from 0 to infinity but not negative numbers. This means the number -5 is not a whole number because even then this does not include a fraction it is a negative number. According to this, this number is an integer (it does not include fractions), a rational number (it can be expressed as a fraction), and a real number (it can be represented in a line), but not a whole number.
Answer:
x=5,y=-12
Step-by-step explanation:
You add the two equations to get: 4x=20
Then you get x=5.
You plug this in to x-y=17 to get y=-12
The answer is x=5 and y=-12
The answer would be D)90 degrees

Answer: 5040</h3>
Explanation:
There are 7 ways to pick the first place position, then 6 ways for second place, 5 for third, and so on. We count down until we get to 1
7,6,5,4,3,2,1
Multiply out those values to get the final answer. On many calculators this can be done using the factorial button, indicated as an exclamation mark
7! = 7*6*5*4*3*2*1 = 5040
