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.

Evaluate for f(5)
Need Answers ASAP
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) = 9Step-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
f(5) = 9Hope this helps you

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

which segment is longer, please explain
Answer:
Blue, if you look, they both are close, but due to the pathagrium theory blue is longer.
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 = ?
Answer:
Let 0.12 be x.
Here, x is recurring in two decimal places so we'll multiply it by 10-
10x = 1.22Now, 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]

The 2 given angles are same- side interior angles and are supplementary, thus
9x - 4 + 5x + 16 = 180, that is
