Answer:
12 of the 5 cents stamps,
20 of the 6 cents stamps
15 of the 8 cents stamps
10 of the 30 cents stamps.
Step-by-step explanation:
Let's name:
x = number of 5 cent stamps,
w = number of 6 cent stamps,
y = number of 8 cent stamps,
z = number of 30 cent stamps,
Create the following system of equations based on the info provided:
z + 5 = y
w = 2 * z
x = 12
600 = 5 (12) + 6 w + 8 y + 30 z
replace everything in terms of "z":
600 = 60 + 6 (2 * z) + 8 (z + 5) + 30 z
540 = 12 z + 8 z + 40 + 30 z
500 = 50 z
z = 10
and now we can find the rest:
y = 5 + 10 = 15
w = 2 * 10 = 20
Therefore there are:
12 of the 5 cents stamps,
20 of the 6 cents stamps
15 of the 8 cents stamps
10 of the 30 cents stamps.

Answer:
x= 4
Step-by-step explanation:
2x + 3( 5x - 7) = 47
2x + 15x - 21 = 47
17x -21 = 47
17x = 47 + 21
17x = 68
x = 68 / 17
x = 4
hope it helps plzz mark me brainliest
Answer:
X = 4 plz brainliest
Step-by-step explanation:
2x+3(5x-7)=47
Distribute
2x + 15x - 21 = 47
Combine like terms
17x -21 = 47
Add 21 to both sides
17x = 68
Divide by 17 both sides
X = 4

65x3 + 450x4=
Step-by-step explanation:
195+1800=1995
Answer:
1,955 miles
Step-by-step explanation:
For this problem all we have to do is, assuming they were constantly going that speed and never stopped, multiply the items and the mph.
SO, to the airport is 65mph*3 hours, which would give 195 miles.
Then, To their destination, 450mph * 4hours = 1,800 miles
Now all that is left to do is add
195 + 1,800 = 1,995
1,995 miles

IN YOUR OWN WORDS How can you use function notation to represent a function? How are standard notation and function notation similar?
Standard Notation:
y = 2x + 5
Function Notation:
f ( x ) = 2x + 5
Please help, due tomorrow
Answer:
Step-by-step explanation:
N^2-10n+9
The function notation to represent a function is f(x) and standard notation and function notation are similar because y = f ( x).
What is function notation?Function notation is a way in which a function can be represented using symbols and signs. Function notation is a simpler method of describing a function without a lengthy written explanation. The most frequently used function notation is f(x) which is read as “f” of “x”. In this case, the letter x, placed within the parentheses and the entire symbol f(x), stand for the domain set and range set respectively.
What is domain?The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
According to the question
Standard Notation:
y = 2x + 5
Function Notation:
f ( x ) = 2x + 5
Function notation can be used to represent the function as it represent function using symbols and signs .
An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”;
that is, y = f ( x).
This last expression is read as “ y equals f of x” and means that y is a function of x.
Standard notation and function notation are similar because
An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”;
that is, y = f ( x).
Hence, function notation to represent a function is f(x) and standard notation and function notation are similar because y = f ( x).
