The scale of a room in blueprint is 3in 5ft. A wall in the same blueprint is 18in. what are the actual room measurements?
QveST [7]

Answer:

Actual length of wall = 30ft

Step-by-step explanation:

We have scale of a room as 3 inch for 5ft.

We can write scaling factor as:

Scaling factor = 3 /60     (Since 5ft = 60 inches )

Scaling factor = 1/20

Now,

a wall in the blueprint is 18inch.

So actual length of wall can be determined by dividing 18 inch by the scale factor.

i.e actual length of wall = 18 / scale factor  = 18 / (1/20)

 actual length of wall = 18* 20 = 360 inch = 30ft (Since 360 inch = 30ft)

Hence Actual length of wall = 30ft

25 — 3x = 40<br> x =<br><br> Please answer quick thanks
Keith_Richards [23]

Answer:

x=-5

Step-by-step explanation:

-3x+25=40. You want to isolate x so you have to subtract 25 from both sides. -3x=15. We then want x to be isolated so we have to divide both sides by -3 to make x by itself. x=-5. Therefore, x=-5.

The sum of a number 1/6 of that number 2 1/2 of that number and seven is 12 1/2 find the number
Zigmanuir [339]

Answer:

Step-by-step explanation:

x = the number

x + 1/6x + 2 1/2x + 7 = 12 1/2

3 + (1/6 + 1/2)x = 12 1/2 - 7

3 + (1/6 + 3/6)x = 5 1/2

3 2/3x = 5 1/2

x = (11/2) / (11/3)

x = 11 / 2 * 3 / 11

x = 3/2

x = 1 1/2
