4 0

Solution 1. 4.896 meters. Sample reasoning: The actual height is 48 times the scaled height. . 4,896 mm is 4.896 m.

102 mm is 0.102 m. The actual train is 48 times 0.102 m. .

2. No. Sample explanation: The modern train needs tracks that are 60 inches apart, because 1 1/4 x 48 =60 . The old tracks are only 54 inches, so they are not wide enough.

Amanda [17]

The fabric cost $181.875

Step-by-step explanation:

Blue fabric bought = 3 3/4 yards , change to improper fraction (4*3)+3/4 = 15/4 yards

Red fabric= 12 5/6 yards = 77/6 yards

Purple fabric= 7 2/3 yards= 23/3 yards

Find  total length of fabric bought, 15/4 +77/6 +23/3 =291/12 yards

Cost per yard= $7.50

Total cost will be, 291/12 * 7.50 =$ 181.875

Select steps that could be used to solve the equation 1 + 3x = -x + 4.
Olegator [25]

Answer:

A, C & D

Step-by-step explanation:

A) 1 + 3x = -x + 4  {subtract 1}

  1 + 3x -1 = -x + 4 - 1

       3x     = -x + 3         {add x}

     3x + x = -x + 3 + x

        4x    = 3       {Divide by 4}

       4x/x = 3/4

x = 3/4

C) 1 + 3x = -x +4            {Add x}

  1+ 3x + x = - x +4 + x      

   1 + 4x  = 4    {subtract 1}

        4x = 4 - 1

        4x = 3   {Divide by 4}

D) 1 + 3x = -x + 4        { Subtract 3x}

         1    = -x + 4 -3x

         1 = -4x + 4          Subtract 4}

      1 - 4 = -4x

        -3 = -4x              {Divide by -4}

       -3/-4 = x

x = 3/4  

          x = 3/4
