A scale model of a bus is 12 inches long. The scale is 1:21. How many inches long is the bus it
represents?
its 304.8 milimeter
The actual length of the bus that the scale model represents is 252 inches.
To find the actual length of the bus represented by the scale model, you can use the scale ratio.
Given:
Scale model length = 12 inches
Scale ratio = 1:21
Let "x" be the actual length of the bus.
Using the scale ratio:
Scale model length / Actual length = Scale ratio
12 inches / x inches = 1/21
Now, solve for "x":
x = 12 inches / (1/21)
x = 12 inches × 21
x = 252 inches
Therefore, the actual length of the bus that the scale model represents is 252 inches.

Step-by-step explanation:
D = b² - 4ac
#1D = 10² - 4 · 3 · 2
D = 100 - 24
D = 76
#2D = (-5)² - 4 · 1 · (-4)
D = 25 - (-16)
D = 26 + 16
D = 42
#3D = 7² - 4 · 1 · (-8)
D = 49 - (-32)
D = 49 + 32
D = 81
#4D = 0² - 4 · 1 · (-9)
D = 0 - (-36)
D = 36
#5D = (-6)² - 4 · 5 · 10
D = 36 - 200
D = - 164

Your answer
Answer:
m = -6
Step-by-step explanation:
2 (m + 7) = -4 - m
2m + 14 = -4 - m
3m + 14 = -4
3m = -18
m = -6
Hopefully this helps!
Brainliest please?
Answer:
m = -6
Step-by-step explanation:
To solve this equation for m, we multiply out the left side to remove the parentheses:
2m + 14 = -4 - m
Next, we combine like terms: 2m and -m are like terms, as are 14 and -4:
3m = -18
Dividing both sides by 3 yields m = -6

Answer:
Question 1 : B) (8 x 20) - (8 x 1)
Question 2 : D) (2 x 9) + (2 x 3)
Step-by-step explanation:
Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1, since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).
-kiniwih426
Answer:
B) (8 x 20) - (8 x 1)
D) (2 x 9) + (2 x 3)
Step-by-step explanation:
Distributive Property: "The distributive property tells us how to solve expressions in the form of a(b + c)."
___________________
Step 1: 8 x 19 = 152
Using PEMDAS, you can see which order to solve the equations in.
PEMDAS tells us to solve whatever is within the parenthesis first but there are 2 parenthesis and both have multiplication so just solve the first parenthesis first;
8 x 20 = 160
Step 2: We now have to solve the second parenthesis;
8 x 1 = 8
Step 3: Using PEMDAS, we see that after we solve the parenthesis, we do subtraction. So subtract 8 from 160.
160 - 8 = 152
So your answer is B) (8 x 20) - (8 x 1).
___________________
Step 1: 2(9 + 3)
Using the Distributive property, we multiply 2 by 9 and 3;
2 x 9 = 18
2 x 3 = 6
Now you are left with 18 + 6.
18 + 6 = 24
So your answer is D) (2 x 9) + (2 x 3).

Richard and Teo have a combined age of 31. Richard is 13 years older than twice​ Teo's age. How old are Richard and​ Teo?
Answer:Teo is 6 and Richard is 25
Step-by-step explanation: Let R and T stand for Richard and Teo's ages. We are told:
R+T=31
R=2T+13
Substitute:
R+T=31
2T+13+T=31
3T+13=31
3T=18
T=6
Since R+T=31, R+6=31, and R = 25

Internal angles of a triangle = 180 degrees
So knowing this we can form the following equation
(x + 26) + (x + 14) + (4x - 10) = 180
Simplify
(x + x + 4x) + (26 + 14 - 10) = 180
6x + 30 = 180
Rearrange for x
6x = 180 - 30
6x = 150
x = 25

17. Solve the following equation. (1 point)
3(y – 5) + 2 = 5
Oy=4
Oy=7
Oy= 4
Oy=6
Answer:
y = 6
Step-by-step explanation:
[tex]3(y - 5) + 2 = 5 \\ 3y - 15 + 2 = 5 \\ 3y - 13 = 5 \\ 3y = 5 + 13 \\ 3y = 18 \\ \\ y = \frac{18}{3} \\ \\ y = 6[/tex]
I hope I helped you^_^
The solution of the equation 3(y - 5) + 2 = 5 gives the result y = 6.
Thus, option (d) is correct.
An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign (=).
Let's solve the equation step by step:
3(y - 5) + 2 = 5
First, distribute the 3 on the left side:
3y - 15 + 2 = 5
Combine the constants on the left side:
3y - 13 = 5
Now, isolate the variable y by adding 13 to both sides:
3y = 18
Finally, divide both sides by 3 to solve for \(y\):
y = 18/3
y = 6
So, the solution to the equation is y = 6.
Thus, option (d) is correct.
