Answer:
6.84%
Step-by-step explanation:
we know that
In this problem
Tara's monthly income ($3,200) represent the 100%
so
using proportion
Find out what percentage represent $219
Let
x ----> the percentage that represent $219
The answer to your question is A. rational numbers.
Rational numbers are closed under any set of operations.
Integers are not closed under division because 1/2 is not an integer.
The set {-1, 0, 1} is also not closed under division because -1/5 does not fall in that set.
Whole numbers are not closed under division because 5/3 will produce a number that is not a whole integer.
Your answer is A. rational numbers.
Answer:
fourth option
Step-by-step explanation:
Given
3x < - 9 ( divide both sides by 3 )
x < - 3
solution set is { x | x < - 3 }
Answer:
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. y=6 is a straight line perpendicular to the y-axis at point (0,6) , which means that the range is a set of one value {6} .
First, let's put all of the variables together.
4m + 5m + 5 + 40 = 180.
Add them.
M is the same multiplier, so we can add 4 and 5 together to make 9m.
Add 5 and 40.
9m + 45 = 180.
From here, we can go two ways. I will show the first way, which is my personal preference.
We want to get rid of the coefficient on m to isolate it, so we must divide it by its coefficient. The coefficient on m is 9. So, divide m by 9. We must also divide everything else by 9.
9m/9 = 1m
45/9 = 5
180/9 = 20
Plug it in--
m + 5 = 20.
Subtract the 5 from both sides to isolate m.
m = 15.
