  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-1, -13)

Point (-1, 21)

<u>Step 2: Find distance </u><em><u>d</u></em>

  1. Substitute in points [DF]:                    \displaystyle d = \sqrt{(-1+1)^2+(21+13)^2}
  2. (Parenthesis) Add:                              \displaystyle d = \sqrt{(0)^2+(34)^2}
  3. [√Radical] Simplify:                             \displaystyle d = \sqrt{(34)^2}
  4. [√Radical] Evaluate:                           \displaystyle d = 34

Answer:

8.333333

Step-by-step explanation:

 3x+2(4+6x)=133

  3x+8+12x=133                      First I distibuted the 2 too the 4 and 6x

15x+8=133                                 Then I added the x es 3x and 12x

15x+8-8=133-8                         Then I subracted 8 from both sides

15x=125                                    That leaves with this

 15x/15=125/15                          Now I divide 15 from both sides to isolate x

x= 8.33333                                 that is the answer

                             check

                  3x+2(4+6x)=133

                 3*8.333333+2(4+6*8.333333)=133

                  24.999999 +2(4+ 49.999998)=133

                    24.999999+2( 53.999998)=133

                         24.999999+107.999996=133

                              132.999995=133

Taylor baked a cake to serve after dinner. Suppose she cut the cake into 8 equal size pieces and 6 people ate all the pieces.exp
REY [17]
All you need to do is 8 divided by 6. When you do so you get: 1.3 which could also be written as 1 3/8.

So each person gets 1 whole piece and 3/8 of another piece.
