Answer:
x = 10
Step-by-step explanation:
With UW extended to point X, then
∠VWX is an external angle of the triangle.
The external angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
∠VWX = ∠WUV + ∠UVX ← substitute values
6x - 19 = 3x + 3 + x - 2, that is
6x - 19 = 4x + 1 (subtract 4x from both sides )
2x - 19 = 1 ( add 19 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Answer:
you would write 2.20x = 22

Answer:
$21.59
Step-by-step explanation:
Basically how I did it was to multiply 5.08 by 4, because that would be the cost of 16 bags and then I divided 5.08 by 4 to see how much one bag would cost. One bag costs 1.27. After I've got the answer, I added 1.27 to 20.32 and got $21.59.
Answer:
Length = 16 feet.
Width = 7 feet
Height = 8 feet
Volume = 896 cubic feet.
Step-by-step explanation:
There is a rectangular prism boiler room. 112 square feet is the floor area of the room.
Let the length of the room is L feet and width is W feet.
So, LW = 112 ...... (1)
Now, given that L = 2 + 2W ........ (2) , hence, from equation (1) we get
(2 + 2W)W = 112
⇒ 2w + 2w² = 112
⇒ W² + W - 56 = 0
⇒ (W +8)(W - 7) = 0
⇒ W = 7 feet. {Neglecting the negative root as W can not be negative}
Hence, from equation (2) we get L = 2W + 2 = 16 feet.
Now, 1 foot more than the width is the height H.
Hence, H = 7 + 1 = 8 feet.
Therefore, the volume of the room is, V = LWH = 16 × 7 × 8 = 896 cubic feet. (Answer)
