<h3>
Answer: C) integers and rational numbers</h3>
Explanation:
The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically any number that does not have a decimal or fractional part to it. We can say that this set is composed of positive and negative whole numbers along with 0. So this is why -3 is in the set of integers.
The value -3 is not in the set of whole numbers because the set of whole numbers is {0, 1, 2, 3, 4, 5, 6, ...}, so this rules out choice D.
Choice B is also eliminated because -3 is a rational number. We can write -3 as a fraction of two integers, example: -3 = -3/1. Any rational number is not irrational, and vice versa.
Choice A is ruled out because it's not the most complete answer (though its technically true).
Answer:
The number of wrapping paper sold was 32 and the number of magazines sold was 40
Step-by-step explanation:
Let
x ----> the number of wrapping paper sold
y ----> the number of magazines sold
we know that
The classes sold 72 items
so
----> equation A
The classes earned $222 for their school
so
----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is (32,40)
see the attached figure
therefore
The number of wrapping paper sold was 32 and the number of magazines sold was 40
Answer:
Step-by-step explanation:
Here you go mate
∴Use PEMDAS
Parenthesis,Exponent,multiplication,Division,Addition,Subtraction
Step 1
5(x+1)>50 Equation/Question
Step 2
5(x+1)>50 Remove parenthesis
5x+5>50
Step 3
5x+5>50 Subtract 5 from sides
5x>45
Step 4
5x>45 Divide sides by 5
Answer
x>9
Hope this helps
Alright, lets get started.
We have given point (8, -15). It lies in Q4.
Please refer the diagram attached.
The hypotenuse of the right angle triangle could be found with help of Pythagorean theorem.
d = sqrt (8^2 + 15^2)
d = sqrt (64 + 225)
d = sqrt 289
d = 17
sin Ф = opposite / hypotenuse
sin Ф = -15 / 17 : Answer
Hope it will help :)
subtract 2 1/4 from 8 1/2
make fractions have same denominator
8 1/2 = 8 2/4
8 2/4 - 2 1/4 = 6 1/4 more pounds
