a roller coaster has four cars each with the same number of seats. these are 21 passengers seated in the roller coaster, but 3 seats are empty. write an equation that can be used to determine the number of seats in each car, s
what would that be as an algebraic expression? ​

Answers

Answer 1

Given:

Number of passengers seated in the roller coaster = 21

Empty seats = 3

Number of cars in roller coaster = 4 (each with the same number of seats)

To find:

An equation that can be used to determine the number of seats in each car.

Solution:

Let s be the number of seats in each car.

Total number of seats in 4 cars = 4s

Using the given information,

Total number of seats = Occupied seated + Empty seats

                                   = 21 + 3

                                   = 24

Now, the required equation is

[tex]4s=24[/tex]

Therefore, the required equation is [tex]4s=24[/tex].

Divide both sides by 4.

[tex]s=\dfrac{24}{4}[/tex]

[tex]s=6[/tex]

Therefore, the number of seats in each car is 6.

Need Answers ASAP

Answers

Answer:

f(5) = 9

Step-by-step explanation:

To evaluate f(5) substitute x = 5 into f(x), that is

f(5) = (5 - 2)² = 3² = 9

Answer:

f(5) = 9

Step-by-step explanation:

f(x) = ( x - 2)²

To find f(5) substitute the value of x that's 5 into f(x). That's for every x in f (x) replace it with 5

That's

f(5) = ( 5 - 2)²

= 3²

We have the final answer as

if y varies directly with x, and y = -20 and x = 5, what is x when y = -30

Answers

Answer:

7.5

Step-by-step explanation:

The value of x = 7.5 when y = -30

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Given that y varies directly with x, and y = -20 and x = 5,

To determine the value of x = 7.5 when y = -30

Direct variation equations can be written as:

y = kx where "k" is a constant.

Substitute the values of y = -20 and x = 5 in the direct variation equation and solve for k:

⇒ -20 = 5k

⇒ k = -20/5

⇒ k = -4

The direct variation equation :

⇒ y = -4x

Substitute the values of y = -30 in the above equation and solve for x:

⇒ -30 = -4x

⇒ 4x = 30

⇒ x = 30/4

⇒ x = 7.5

Thus, the value ofx = 7.5 when y = -30

Answer:

Step-by-step explanation:

Answer:

Red is longer

Step-by-step explanation:

With the distance equation formula, you can find this. The distance equation formula is d=[tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} } \\[/tex]. (x1,y1)(x2,y2) are the coordinates of each individual point.

If you turn the grid into a graph, red's points would be (0,0)(3,3)

Blue's points would be (0,3)(-1,-1). Using the distance formula blue is [tex]\sqrt{17}[/tex].

The red is [tex]\sqrt{18}[/tex], so red is longer.

Write 0.12 as a fraction.
Let x = ?
100x = ?
100x - x = ? - ?
99x = ?
X = ?

Let 0.12 be x.

Here, x is recurring in two decimal places so we'll multiply it by 10-

10x = 1.22

Now, by subtracting them-

[tex] \\ \implies \sf \: 10x - x = 1.22 - 0.12 \\ \\ \\ \implies \sf \: 9x = 1.1 \\ [/tex]

Now, we'll divide both sides by 9 to get x as a fraction -

[tex] \\ \implies \sf \: x = \frac{1.1}{9} \\ \\ \\ \star \: \large{ \boxed{ \sf{x = \frac{11}{90} }}} \\ [/tex]
