Action video rents dvds and video games to its customers. The cost to rent d, DVD movies, is $3.50 each and the cost to rent r, video games, is $2.50 each. Which of these represents the possible number of DVDs that could be rented for no more that $20?
Answers
Answer:
d = 5.71
Step-by-step explanation:
Let
Quantity of DVD movies = d
Quantity of Video games = r
Price of DVD movies = $3.50
Price of video games = $2.50
Total budget plan for DVD movies= $20
Which of these represents the possible number of DVDs that could be rented for no more that $20
Price of DVD movies × Quantity of DVD movies = $20
$3.50 × d = $20
3.50d = 20
Divide both sides by 3.50
d = 20/3.50
= 5.71

What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
2x + 4 - 5x is an expression.
3x = 4 is an expression.
We have,
We will find the value of the expression when x = 3.
2x³ = 2 x 3³ = 2 x 3 x 3 x 3 = 64
2x³ + 5 = 2 x 3³ + 4 = 64 + 4 = 68
(2x)³ = 2³ x 3³ = 8 x 27 = 216
(x - 1)³ = (3 - 1)³= 2³ = 8
We see that,
2x³ has the greatest value.
Thus,
The expression that has the greatest value is 2x³

Answers
(43 1/8) / (5 3/4) = 7 1/2
The number of miles is 7 1/2 miles option (A) is correct if Tyler rode his bike 43 1/8 miles in 5 3/4 hours
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Tyler rode his bike 43 1/8 miles in 5 3/4 hours.
Let d is the number of miles Tyler ride his bike per hour
43 1/8 miles in 5 3/4 hours
345/8 miles in 23/4 hours
d miles in 1 hour
345/8 = 23d/4
345/2 = 23d
d = 345/46
d = 322/46 + 23/46
d = 7 1/2 miles
Thus, the number of miles is 7 1/2 miles option (A) is correct.

Point E is between segment DF. The length of DE is 3x - 1, EF is 13 and DF is 6x, find DF.
Answers
Answer:
The correct answer to this problem is x = 4.
Step-by-step explanation:
To solve this problem, we can set up an equation using the given information. We know that Point E lies along the segment DF, so we can write:
DE + EF = DF
Now, we can substitute the values given into our equation.
(3x-1) + (13) = 6x
The next step is to eliminate the parentheses and combine like terms on the left side of the equation.
3x - 1 + 13 = 6x
3x + 12 = 6x
Next, we should subtract 3x from both sides to move all of the variable terms to the right side of the equation.
12 = 3x
Finally, we can divide both sides by 3, in order to completely isolate the variable x on the right side of the equation.
4 = x
Therefore, the correct answer is x = 4.

The area of a square is given by A=s2, where s is the length of each side of the square. If the area of a square room is 81 square meters, what is the length of one side of the room in meters?
Answers
Answer: The length of one side is 9m.
Step-by-step explanation:
If area is 81 square meters, that means A = 81 m^2.
Since A = s^2, we can substitute s^2 for A. Then
(s^2) = 81 m^2
Take the square root of both sides to solve for s:
(s^2)^(1/2) = (81 m^2)^(1/2)
s = 9 m

Step 1. G is the second letter, so we first use the equation g(x) = x-4
Step 2. Plug in ten for x. g(x) = 10-4
Step 3. ten minus four is six. g(x) = 6
Step 4. Now the new x is 6 and we use the second equation next.
f(x) = x^2 + 1
Step 5. Plug in six for x. f(x) = 6^2 + 1

The answer is
81x⁴ + 216x³ + 216x² + 94x + 16Step-by-step explanation:
(3x + 2)⁴
Using the Pascal's triangle
For an exponent of 4 we have
( a + b)⁴ = a⁴ + 4a³b + 6a²b² + 4ab³ + b³
Using a = 3x and b = 2 we have
( 3x +2)⁴ = ( 3x)⁴ + 4 [ (3x)³(2) ] + 6[ (3x)²(2)²] + 4 [ 3x(2)³ ] + 2⁴
Expand and simplify
That's
➢ ( 3x +2)⁴ = 81x⁴ + 4[ (27x³)(2) ] + 6 [ (9x²)(4) ] + 4 [ 3x(8) ] + 16
➢ 81x⁴ 4( 54x³) + 6(36x²) + 4( 24x) + 16
