Step-by-step explanation: The standard formula for geometric sequence is an = a1 * r^(n-1) where r is the geometric factor and n is an integer. In this problem, upon substitution, an = 4*2^(n-1).
Alison have 100 baseballs cards .
- A expression is a statement containing at least two numbers/variables and at least one mathematical operation.
- An expression is a combination of terms combined by mathematical operations such as subtraction, addition, multiplication, and division.
- The terms that appear in the formula are:
- Constant: A constant is a fixed number.
- Variables: Variables are symbols that do not have fixed values.
- Term: A term can be a single constant, a single variable, or a combination of variables and constants combined with multiplication or division.
- Coefficient: A coefficient is a number that is multiplied by a variable in an expression.
Let the number of footballs cards Alison have be "x".
It is given that Allison has 5 times as many baseball cards as football cards which can be represented by an expression given by
number of baseball cards = 5 × number of football cards
number of baseball cards
...(1)
She has total of 120 baseball and football cards which can be represented by an expression given by
Baseball cards + football cards = 120
![5x+x=120\\6x=120\\x=20](https://tex.z-dn.net/?f=5x%2Bx%3D120%5C%5C6x%3D120%5C%5Cx%3D20)
From equation (1) , put x = 20 we get
Baseball cards = ![5\times20](https://tex.z-dn.net/?f=5%5Ctimes20)

Answer:
just focus. concentrate and use your notes. i promise you will find the answer
Step-by-step explanation:
I would like to help you, but you have to show the value of the sides of the triangle.
The perimeter formulas is :
P= a+b+c
Now, look the picture of the triangule you might have and it doesn’t show in here and see the values of each side and follow the formulas and resolve the equation to check what’s the right answer. If you give me the values of each side I can help you.
