What is the slope of the line that passes through the points (-10, -8)(−10,−8) and (-8, -16) ?(−8,−16)? Write your answer in sim
photoshop1234 [79]

The slope of the line that passes through points ( -10, -8 ) and ( -8, -16 ) is -4.

<u>Explanation:</u>

Points given = ( -10, -8) and ( -8, -16)

Slope = ?

( -10, -8 ) : x1 = -10 and y1 = -8

( -8, -16 ) : x2 = -8 and y2 = -16

We know,

slope = y2 - y1 / x2 - x1

Slope = -16 - ( -8) / -8 - (-10)

slope = -16 + 8 / -8 + 10

slope = -8 / 2

slope = -4

Therefore,  slope of the line that passes through points ( -10, -8 ) and ( -8, -16 ) is -4.

the cost C (in dollars) of making n watches is represented by C = 15n + 85. How many watches are made when the cost is $385?
liberstina [14]
20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.

Friday's meeting needs 12 more sandwiches than Tuesday which needs 6 fewer than Monday which needs 20 more than wednesday which
Alina [70]

He will need 315 sandwiches to make each day next week

Step-by-step explanation:

The given:

  • Friday's meeting needs 12 more sandwiches than Tuesday
  • Tuesday needs 6 fewer than Monday
  • Monday needs 20 more than Wednesday
  • Wednesday needs 5 fewer than Thursday
  • The number of sandwiches ordered for the meeting that calls for the fewest is 50

We need to find how many sandwiches he will need to make each day next week

Assume that Tuesday needs x sandwiches

∵ Friday's meeting needs 12 more sandwiches than Tuesday

∵ Tuesday needs x sandwiches

- Add x by 12 to find Friday's need

∴ Friday needs = x + 12

∵ Tuesday needs 6 fewer than Monday

- That means Monday needs 6 more than Tuesday, add 6 to x

   to find Monday needs

∴ Monday needs = x + 6

∵ Monday needs 20 more than Wednesday

- That means Wednesday needs 20 less than Monday, subtract

   20 from Monday needs to find Wednesday needs

∴ Wednesday needs = x + 6 - 20 = x - 14

∵ Wednesday needs 5 fewer than Thursday

- That means Thursday needs 5 more than Wednesday, add 5 to

    Wednesday needs to find Thursday needs

∴ Thursday needs = x - 14 + 5 = x - 9

∵ The number of sandwiches ordered for the meeting that calls

   for the fewest is 50

- From the days needs above the fewest one is Wednesday, then

   equate Wednesday needs by 50

∵ Wednesday needs is x - 14

∴ x - 14 = 50

- Add 14 to both sides

∴ x = 64

Substitute x in each day needs to find the number of sandwiches

∵ Tuesday needs is x

∴ Tuesday needs = 64

∵ Friday needs is x + 12

∴ Friday needs = 64 + 12 = 76

∵ Monday needs is x + 6

∴ Monday needs = 64 + 6 = 70

∵ Wednesday needs = 50

∵ Thursday needs is x - 9

∴ Thursday needs = 64 - 9 = 55

Add the numbers of sandwiches of all day to find the number of sandwiches he will need to make each day next week

∵ The number of sandwiches = 76 + 64 + 70 + 50 + 55

∴ The number of sandwiches = 315

He will need 315 sandwiches to make each day next week

can someone help me with these??? I really appreciate it!!! I did one of them already. ( if the first one is wrong can someone p
Anestetic [448]

Answer:

the answer to your questions are below

Step-by-step explanation:

1.-

          x = 3x - 60

        3x - x = 60

            2x = 60

             x = 30

            A = 30

2.-  

        - x + 26 = 2x - 10

       2x + x = 26 + 10

       3x = 36

        x = 36/3

        x = 12

        D =  2(12) - 10

        D = 24 - 10

        D = 14

3.-

    5x + 10 = 7x - 12

   7x - 5x = 10 + 12

          2x = 22

          x = 22/2

          x = 11

4.-   4x + 7 = 5(x - 4)

      4x + 7 = 5x - 20

      5x - 4x = 7 + 20

            x = 27

5.- 6(x - 2) = 3x + 30

    6x - 12 = 3x + 30

    6x - 3x = 30 + 12

           3x = 42

           x = 14

 DHG = 6(14 - 2)

DHG = 6(12)

DHG = 72

0.194 with 94 repeating into a fraction?
ruslelena [56]
X = 0.194_94
100x = 19.494_94
100x -x = 99x = 19.3
x = 19.3/99
x = 193/990 . . . . . this fraction does not reduce.
