I believe the length of the actual room would be 12 ft.

To figure this out, first find how many feet one inch represents.
8/2, or 4 feet. <
Then, we have 3 inches. Since 1 inch represents 4 feet, 3 inches must represent 12 feet, as 3*4=12.

Hope this helped! :)

2 in: 8 ft simplifies to 1 in: 4 ft which is just generally easier to work with.

1 in: 4 ft = 3 in: x ft

x ft= 4*3 = 12

The length of the actual room is 12 feet.

Hope this helps!

Answer: The toy should be 2.4 inches tall

------------------------------------
------------------------------------

Explanation:

First convert 6 ft to inches
6 ft = (6 ft)*(12 in/1 ft) = (6*12) inches = 72 inches

So, 6 ft = 72 inches

The toy is manufactured with a scale of 1:30 meaning that the toy is 1 unit tall compared to the soldier which is 30 units tall. The soldier is 30 times taller than the toy. We can therefore form the ratio

1/30 = x/72

where x is the height of the toy soldier in inches

Cross multiply and solve for x

1/30 = x/72
1*72 = 30*x
72 = 30*x
72/30 = 30*x/30
72/30 = x
x = 72/30
x = 12/5
x = 2.4

So the toy should be 2.4 inches tall.

Note how 30 times 2.4 gives us
30*2.4 = 72
which fits with the theme that the real soldier is 30 times taller than the toy counter part.

Four times a first number decreased by a second number is - 14. The first
mel-nik [20]

Answer:

f = -5, s = -6

Step-by-step explanation:

F= first number

S= second number

4f - s = -14

f + 3s = -23

3(4f - s = -14)

12f - 3s = -42

+ f + 3s = -23

13f = -65

————

13

f = -5

4f - s = -14

4(-5) - s = -14

-20 - s = -14

+20 +20

-s = 6

———

-1

s = -6
