I need to know what the value is for x

Mathematics

4/6 = x + 3/ 12 - x
4( 12 - x) = 6( x + 3)
48 - 4x = 6x + 18
-4x - 6x = 18 - 48
- 10x = -30
x = 3

let x be the number you're trying to solve.
(x/100)25 = 15
x/4 = 15
x = 15(4)
x = 60

The pitch of the roof is given by the ratio of the rise to the run of the roof, which is the slope of the rafter

The \ pitch  \ of  \ the \  roof  \ is \ \mathbf {\dfrac{6}{13}}

Please find attached the simple <u>diagram of the house</u> with all measurements labeled

The reason the above value for the pitch and the diagram are correct are as follows:

The given parameters are;

Width of the section of the house on which the gable of the roof is to be placed = 50 feet

Length of the over hang on the sides of the roof = 1 foot each

Total span of the roof = 52 feet

Horizontal length of each rafter, the run = 26 feet

The height of the ridge above the top of the frame, the rise = 12 feet

Required:

  • To find the pitch of the roof
  • To draw a diagram of the house showing measurements

Solution:

Pitch = \dfrac{Rise}{Run}

  • Pitch  \ (slope) \ of \ roof =  \dfrac{12}{26} =\dfrac{6}{13}

Please find attached the <u>diagram</u> of the house showing the measurements for the roof parameters and the section of the house where the gable roof is to be placed

Answer the 3 questions above (in the picture) please!!!
Karo-lina-s [1.5K]

Answer:

1. X = 17/A  --- answer is (A)

2.  (6, 0.7) (10, 1.9)

3. $10.99D + $9.99  ≤ $100

Step-by-step explanation:

1. AX + 4AX = 51 + 2AX

 5AX = 51 + 2AX .... -2AX both side

3AX = 51   .. divide 3A

X = 17/A  --- answer is (A)

2. 10y = 3x -11

   (2, 0.5):       3*2 -11 = - 5     10y = 10*0.5 = 5    ..... not correct

    (4, 1)            3*4 - 11 = 1       10y = 10*1 = 10 ....... not correct

   (6, 0.7)        3*6 - 11 = 7       10y = 10*0.7 = 7  .....Correct

   (8,2.3)          3*8 -11 = 13       10y = 10*2.3 =23   ..... not correct

   (10, 1.9)        3*10 -11 = 19       10y = 10*1.9 = 19   .... correct

3.  1D cost $10.99

    D piece cost: $10.99D

     Shipping: $9.99

    No more than $100: ≤ 100

D piece DVD + Shipping withtotal no more than $100:

$10.99D + $9.99  ≤ $100
