1 and 18.
2 and 9.
3 and 6.
Answer:
x=9 or x=-3
Step-by-step explanation:
add one to both sides
take square root of both sides
since (x+3)= + or -6, the add 3 to both sides and subtract 3 to both sides does not matter
I don't think there should be a subtract one from both sides step, but i'm not sure
Answer: No, it is not.
Step-by-step explanation:
In order to solve this exercise it is important to remember the definition of "Integers".
Integers are defined as those numbers that do not have a fractional part. Integers contains:
1. The positive numbers (these are the numbers greater than zero):
![\{1,2,3,4,5...\}](https://tex.z-dn.net/?f=%5C%7B1%2C2%2C3%2C4%2C5...%5C%7D)
2. The negative numbers (these are the numbers less than zero):
![\{-1,-2,-3,-4,-5...\}](https://tex.z-dn.net/?f=%5C%7B-1%2C-2%2C-3%2C-4%2C-5...%5C%7D)
3. The zero:
![\{0\}](https://tex.z-dn.net/?f=%5C%7B0%5C%7D)
It is also necessary to remember the definition of "Decimal numbers".
Decimal numbers are those numbers that have a whole part, a fractional part and a point that separates these parts. That point is called "Decimal point".
Then, given the following number:
![416.60](https://tex.z-dn.net/?f=416.60)
You can identify that it has a whole part and a fractional part separated by the Decimal point. Therefore, that number it is not an Integer.
To find the total cost of Mikayla's purchase, we add together the costs of the skirts and tops. The costs of the skirts can be found be multiplying the quantity bought by the cost per skirt. Same goes for the tops.
5x + 3(9)
Simplified:
5x + 27
I believe the answer would be 70 but make sure just in case.
