Answer:

1. a) 3x + 21 = 6x - 60

  b) x = 27

  c) angle measure = 102º

2. a) 12x - 18 = 8x + 10

   b) x = 7

   c) angle measure = 66º

3. a) 7x + 9 + 5x + 3 = 180 (simplified: 12x + 12 = 180)

   b) x = 14

   c) 107º; 73º

4. a) 3x + 10 + 3x -28 = 180 (simplified: 6x -18 = 180)

   b) x = 33

   c) 109º; 71º

5. a) 12x + 15 = 15x

   b) x = 5

   c) 75º

Step-by-step explanation:

1. a) they're the same angle so set them equal to each other: 3x + 21 = 6x - 60

  b) solve from the equation above

      3x + 21 = 6x - 60        subtract 3x from both sides

       21 = 3x - 60                add 60 to both sides

       81 = 3x                        divide both sides by 3

       x = 27

  c) plug back into each equation (they should be the same, but do both just to check)

      3(27) + 21 = 81 +21 = 102º

      6(27) - 60 = 162 - 60 = 102º

2. a) again, they're the same angle measure so set them equal to each other: 12x - 18 = 8x + 10

   b) solve the equation for x

      12x - 18 = 8x + 10            subtract 8x from both sides

       4x - 18 = 10                     add 18 from both sides

       4x = 28                           divide both sides by 4

       x = 7

  c) plug back into each equation (they should be the same, but do both just to check)

      12(7) - 18 = 84 - 18 = 66º

      8(7) + 10 = 56 + 10 = 66º

3.  a) the sum of the two angles is 180º so 7x + 9 + 5x + 3 = 180

         if you want the equation simplified: 12x +12 = 180

     b) solve for x, i will be using the simplified equation

         12x + 12 = 180            subtract 12 from both sides

         12x = 168                    divide both sides by 12

         x = 14            

     c) plug into each equation to get the two angle measures

         7(14) + 9 = 98 + 9 = 107º

         5(14) + 3 = 70 + 3 = 73º

4. a) the sum of the two angles is 180º so 3x + 10 + 3x -28 = 180

       if you want it simplified: 6x -18 = 180

   b) solve for x, i will be using the simplified equation

       6x - 18 = 180                    add 18 to both sides

       6x = 198                           divide both sides by 6

       x = 33

   c) plug into each equation to get the two angle measures

      3(33) + 10 = 99 + 10 = 109º

      3(33) - 28 = 99 - 28 = 71º

5. a) they're the same angle measure so set them equal to each other: 12x + 15 = 15x

   b) solve for x with the equation above

        12x + 15 = 15x                   subtract 12x from both sides

        15 = 3x                              divide both sides by 3

        x = 5

  c) plug back into each equation (they should be the same, but do both just to check)

      12(5) + 15 = 60 + 15 = 75º

      15(5) = 75º

The zero pairs that can be created in the model 2 x tiles and 1 negative x tile. 3 plus sign tiles and 2 negative tiles is '12'.

A pair of numbers that add up to zero is referred to as a zero pair. The two numbers must contain both a positive and a negative number, according to the concept of a zero pair.

Combination of all zero pair:

The given data is, 2 x tiles and 1 negative x tile. 3 plus sign tiles and 2 negative tiles.

Rewrite the combinations as below,

[x] [-x]   [+] [-]

[x]         [+] [-]

            [+]

Formation of zero pair combinations:

[x][-x]

[-x][x]

1. 678.6

2. 1131

3. 490.1

4. 1809.6

Step-by-step explanation:

A=2πrh+2πr2

Answer:

1.  SA = 216π cm² ≈ 678.24cm²

2. SA = 360π ft²≈ 1130.40ft²

3. SA = 156π yd² ≈ 489.84yd²

4. SA = 576π m² ≈ 1808.64 m²

Step-by-step explanation:

SA of a cylinder = 2πrh + 2πr²

1.  r = diameter ÷ 2

  r = 12/2 = 6

   SA = 2π(6)(12) + 2π(6)²

   SA = 144π + 72π

   SA = 216π ≈ 678.24

2. r = 19/2 = 9

   SA = 2π(9)(11) + 2π(9)²

   SA = 198π + 162π

   SA = 360π ≈ 1130.40

3.  SA = 2π(6)(7) + 2π(6)²

    SA = 84π + 72π

    SA = 156π ≈ 489.84

4. r = 24/2 = 12

    SA = 2π(12)(12) + 2π(12)²

    SA = 288π + 288π

    SA = 576π ≈ 1808.64

Answer:

37

Step-by-step explanation:

A manager gives gift cards to every 80th customer. On Saturday, 1210 customers entered, while on Sunday, 1814 customers entered. We are asked to find the number of people who received gift cards.

Consider Saturday:

(1) Probably the most efficient method is to divide 1210 by 80.

(The first gift card was given to the 80th person and 80/80=1. The second to the 160th person and 160/80=2. The third to the 240th person and 240/80=3, etc...)

So 1210 divided by 80 is 15 with a remainder of 10.

15 people received gift cards on Saturday.

(2) We could set up a linear inequality where the unknown x represents the number of people receiving gift cards. Then 80x<1210 and x<15.125 so x=15.

(3) You could just keep adding, perhaps in a table, until you got to the last person:

(# customers, # gift cards): (80,1), (160,2), (240,3)...(1120,14), (1200,15)

The answer will not change, but the manager can either start counting at zero again on Sunday, or continue from the previous day making the first person in on Sunday number 11.

Again we take 1814 divided by 80 to get 22 with a remainder of 54. (With the additional 10 from Saturday we would have remainder 64, but still not enough people to give out another card.)

15 cards given out Sat with 22 cards given out Sun means that there were a total of 15+22=37 people who received gift cards.
