Answer:
1/5
Step-by-step explanation:
Assuming the total number of all the trick or treaters that came to my house is N and the numbers of trick or treaters were dressed as characters from Star Wars is n.
Given that the portion of trick or treaters were dressed as characters from Star Wars, = 1/3 of all the trick or treaters.
Now, 3/5 of those
dressed as characters from Star Wars were dressed as the character Darth Vader, so
The number of visitors that were dressed as the character Darth Vader
[ by using equation (i)]
Hence, the fraction of all trick or
treaters were dressed as Star Wars and were Darth Vader is 1/5.
Factor out he common term, which in this case is "v"
So your answer would be v(9-1)
I like to always factor out the negative first, so that we will have our first term be positive:
So it can be rewritten as this: -(x^2-3x-28)
Then we need to find two numbers that multiply to -28, but add up to -3.
Those two numbers are -7 and +4.
So we can rewrite as: -(x-7)(x+4)
Answer:
Constant
Step-by-step explanation:
(1,32)
(2,64)
(3,96)
They increase by 32 each time
An algebraic expression is a phrase in mathematics that consists of numbers such as 1,2,3 and the like, variables which are represented with letters and operations like addition, multiplication, subtraction and division. It is usually used to represent a certain situation which would relate the variables involved. To write the algebraic expression for the problem statement above, we do as follows:
Let x = number of consoles to be bought
y = number of games to be bought
z = number of controllers to bebought
C = total cost of all
The total cost would be equal to the sum of the price multiplied by the number of consoles, games and controllers bought. We write the algebraic expression as follows,
C = 299x + 59.99y + 29.99z
