Simplify 2.1/1.5

Step-by-step explanation:

Given

8(x - 1) = - 4x + 136

8x - 8 = -4x + 136

8x + 4x = 136 + 8

12x = 144

x = 144 / 12

x = 12

Step-by-step explanation:

1/2 + 3/8 = 4+3/8 = 7/8

Answer:

7 / 8

Step-by-step explanation:

In order to add fractions, the denominators must be the same.

1 / 2 + 3 / 8

Find the least common denominator by prime factorization.

2:2

8:2, 2, 2

To determine the least common denominator (LCD), multiply the common factor 2 times the other factors in blue.

LCD = 2 × 2 × 2 = 8

Multiply  1 / 2 times 4 / 4 so that it will have a denominator of 8.

1 / 2 × 4 / 4 + 3 / 8

= 4 / 8 + 3 / 8

= 7 / 8

Hope this helps :)

Answer:

Step-by-step explanation:

In parallelogram opposite angles are equal

6x = 66      {Divide both sides by 6}

x = 66/6

x = 11

20y - 46 = 13y + 10     {Add 46 to both sides}

20y - 46 + 46 = 13y + 10 + 46

             20y   = 13y + 56     {Subtract 13y from both sides}

   20y - 13y    = 13y-13y + 56

              7y    =  56    {Divide both sides by 7}

                y =  56/7

y = 8

Answer:

(3x + 4y - 3z)(3x + 4y + 3z)

Step-by-step explanation:

(3x + 4y)² - (3z)² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Here a = 3x + 4y and b = 3z, then

(3x + 4y)² - (3z)²

= (3x + 4y - 3z)(3x + 4y + 3z) ← in factored form

Answer:

see in the pic, we have: E(-5; -3), F(-3; -6), A(-5; -8), B(1,-8), C(3; -5), D(1;0)

=> AB = 6

[tex]bc = \sqrt{(3 - 1) {}^{2} + ( - 5 + 8) {}^{2} } = \sqrt{13} \\ \\ \\ cd = \sqrt{(1 - 3) {}^{2} + ( - 5) {}^{2} } = \sqrt{29} \\ \\ \\ [/tex]

[tex]de = \sqrt{( - 5 - 1) {}^{2} + ( - 3) {}^{2} } = 3 \sqrt{5} [/tex]

[tex]ef = \sqrt{( - 3 + 5) {}^{2} + ( - 6 + 3) {}^{2} } = \sqrt{13} [/tex]

[tex]fa = \sqrt{( - 5 + 3) {}^{2} + ( - 8 + 6) {}^{2} } = 2 \sqrt{2} [/tex]

the perimeter of the shape = AB + BC + CD + DE + EF + FA

[tex] = 6 + \sqrt{13} + \sqrt{29} +3 \sqrt{5} + \sqrt{13} + 2 \sqrt{2} [/tex]

[tex] = 28.13[/tex]

Answer:

16,777,216 bacterias.

Step-by-step explanation:

There are 24 hours in one day, and the given bacteria (1) doubles every hour.

Hour 0: 1

Hour 1: 1 x 2 = 2

Hour 2: 2 x 2 = 4

Hour 3: 4 x 2 = 8

Hour 4: 8 x 2  = 16

Hour 5: 16 x 2 = 32

Hour 6: 32 x 2 = 64

Hour 7: 64 x 2 = 128

Hour 8: 128 x 2 = 256

Hour 9: 256 x 2 = 512

Hour 10: 512 x 2 = 1,024

Hour 11: 1,024 x 2 = 2,048

Hour 12: 2,048 x 2 = 4,096

Hour 13: 4,096 x 2 = 8,192

Hour 14: 8,192 x 2 = 16,384

Hour 15: 16,384 x 2 = 32,768

Hour 16: 32,768 x 2 = 65,536

Hour 17: 65,536 x 2 = 131,072

Hour 18: 131,072 x 2 = 262,144

Hour 19: 262,144 x 2 = 524,288

Hour 20: 524,288 x 2 = 1,048,576

Hour 21: 1,048,576 x 2 = 2,097,152

Hour 22: 2,097,152 x 2 = 4,194,304

Hour 23: 4,194,304 x 2 = 8,388,608

Hour 24: 8,388,608 x 2 = 16,777,216

~

Another way to do it is using exponential functions. If it doubles every hour as such: [tex]2^{x}[/tex]  , in which x is the amount of hours: [tex]2^{24} = 16777216[/tex]

1. 3n+4n=28

         7n=28

           n=4

2. 2x+7-9=10

           2x=10+2

            2x=12

               x=6

3. 3(a+2)=-5

    3a+6=-5

         3a=-11

           a= -11/3

4. 2(3n-1)=19

      6n-2=19

          6n=21

            n=7/2

5. 3x-5-x+1=10

            2x=14

               x=7

6. -3-5=5-2a+7

      2a=20

        a=10

7. -5(n-2)= -15

        n-2=3

           n=5

8. Let the cost of each fan be y.

    6y+3y=1188

What is [tex]\frac{8\sqrt{3}}{2}[/tex]?

we can seperate this to what is 8 * [tex]\sqrt{3}[/tex] / 2

we just cancel out the 2 with the 8. So the answer will be

4[tex]\sqrt3[/tex]

Answer:

180 degree clockwise rotation about center and a dilation of 0.5.

Answer:

(4, 6 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 36 → (1)

y = - [tex]\frac{1}{2}[/tex] x + 8 → (2)

Substitute y = - [tex]\frac{1}{2}[/tex] x + 8 into (2)

3x + 4(- [tex]\frac{1}{2}[/tex] x + 8) = 36 ← distribute and simplify left side

3x - 2x + 32 = 36

x + 32 = 36 ( subtract 32 from both sides )

x = 4

Substitute x = 4 into (2) for corresponding value of y

y = - [tex]\frac{1}{2}[/tex] × 4 + 8 = - 2 + 8 = 6

solution is (4, 6 )

Answer:

12.5 units^2

Step-by-step explanation:

The shape is a trapezoid

The area of a trapezoid is given by

A = 1/2 ( b1+b2)h  where b1 and b2 are the lengths of the bases and h is the height

A = 1/2 ( 2.5+ 7.5) 2.5

A = 1/2 ( 10)2.5

A = 12.5 units^2

Answer:

12.5 units^2

Answer:

x = 2

z = 85°

Step-by-step explanation:

95° + z = 180°

z = 180 - 95

z = 85°

z + (11x + 73) = 180°

85 + (11x + 73) = 180°

11x + 85 + 73 = 180°

11x + 158 = 180°

11x = 180 - 158

11x = 22

x = 22/11

x = 2
