Question is not clear enough
I'll assume the question is this:
A fair coin has 2 sides (heads and tails) that are equally likely to show when the coin is flipped. What is P(tails)?
Answer:
P(tails) = 0.5
Step-by-step explanation:
Given:
Number of sides = 2
Number of head = 1
Number of tails = 1
Let P(Tail) = Probability of obtaining a tail when the coin is flipped.
P(Tails) is calculated as follows;
P(Tails) = Number of Tails/Total Number of Sides
Substitute in the values of Number of Tails and Total Number of Sides
P(Tails) = 1/2
P(Tails) = ½
P(Tails) = 0.5
Hence, the probability of obtaining a tail provided that the two sides of the coin are equally likely to show when the coin is flipped is 0.5
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!
Answer:
62.5
Step-by-step explanation:
1. convert percent value to decimal
30.00/100=.3
2. turn problem into equation where x equals the original price
x*.3=18.75
3. solve
(x*.3=18.750)/.3
x=62.5
To write algebraic expressions
to model quantities is you base the algebraic expressions or mathematical
values declared in words by the manner of how the sentence illustrates the said
problem. For example, one minus a number is the difference of zero shall be
1.
1 – n = 0.
Other same examples, John bought 25 apples while Julia bought only
15 from the market. If Niccole bought twice as much as Julia’s, how many was
Niccole’s apples?

Julia = 15 apples
Niccole = 2Julia
Hence,
2Julia = 2(15) = 30 apples.
