Step-by-step explanation:

Answer:

-19

Step-by-step explanation:

3x+2 = -55

   -2         -2

3x = -55-2

3x = -55+-2

3x = -57

/3      /3

x=-19

Answer:

-19

Step-by-step explanation:

[tex]3x + 2 = -55[/tex]

[tex]3x = -55[/tex]

       [tex]-2[/tex] (2 is negative because it was moved to the other side of the equation)

[tex]3x/3 = -57/3[/tex]   (Divide both sides of the equation by 3 to isolate x.)

[tex]x = -19[/tex]

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

 4/9 kg            $2

------------- = --------------

    1 kg               x

Multiplying both numerators by 9, we get:

  4 kg          $18

------------ = ---------

   1 kg             x

Cross-multiplying, we get 4x kg = $18-kg.  Solving for x, we get:

        $18-kg

x = -------------- = $4.50

         4kg

1 kg of baking soda costs $4.50.

The equation that represents a proportional relationship or a line, is y=kx wher k is the constant of proportionality

The area of the composed figure will be 140 square inches. Then the correct option is D.

Let H be the height and W be the width of the parallelogram. Then the area of the parallelogram will be given as,

Area of the parallelogram = H × W square units

The figure can be composed of different shapes.

The composed figure is a parallelogram. The dimension of the parallelogram is 10 inches high and 14 inches wide base. Then the area of the parallelogram is calculated as,

A = 10 x 14

A = 140 square inches

The area of the composed figure that is a parallelogram will be 140 square inches.

The parallelogram is made from a rectangle. Thus, the correct option is D.

Answer:

Ur answer would be option 4

Step-by-step explanation:

Answer:

A. 10m - 16

Step-by-step explanation:

First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:

3(4m - 2) =

3 * 4m = 12m

3 * -2 = -6

3(4m - 2) = 12m - 6

-2(m + 5) =

-2 * m = -2m

-2 * 5 = -10

-2(m + 5) = -2m -10

Combine like terms:

12m - 6  -2m - 10

12m - 2m - 6 - 10

(12m - 2m) + (-6 - 10)

10m - 16

A. 10m - 16 is your answer.

~

Answer:

10 m - 16 (Answer A)

Step-by-step explanation:

We use distributive property to eliminate parenthesis:

12 m - 6 - 2 m -10

and now combine like terms:

[12 m - 2 m] - 6 - 10

10 m - 16

Therefore, answer option A.  is the correct one

Answer:

question 1 part a =

estimated number of dogs

=6.99 × 107

= 6.99 • 10,000,000

= 69,900,000

estimated number of cats

= 3.61 × 107

= 3.61 • 10,000,000

=36,100,000

estimated number of birds

= 8.3 × 106

= 8.3 • 1,000,000

= 8,300,000

part b = total population of pet dogs, cats, and birds  

= 69,900,000 + 36,100,000 + 8,300,000

= 114,300,000

question 2 part a =

The estimated number of dogs is 6.99 x 10^7 .

The estimated number of cats is 3.61 x 10^7.

The estimated number of birds is 8.3 x 10^6.

The power of  10 in  8.3 x 10^6  is 6, which is less than the power of 10 in the other two numbers. To make the calculation simpler, convert this number so the exponents are all the same.

Multiply and divide 8.3 x 10^6 by 10 to increase its exponent by 1:

8.3 x 10^6 = 10/10 x 8.3 x 10^6

                 = 8.3/10 x 10^6 x 10

                 = 0.83 x 10^7

part b =

total number of pet dogs, cats, and birds

=

6.99 × 107 + 3.61 × 107 + 0.87 × 107

=

(6.99 + 3.61 + 0.83) • 107

=

11.43 • 107

part c =

No. The sum from part B is not in scientific notation.

The total number of pet dogs, cats, and birds is 11,43 x 10^7. To express the number in scientific notation, the decimal point must be moved one digit to the left. To do that, divide and multiply the number by 10:

10/10 x 11.43 x 10^7 = 11.43/10 x 10^7 x 10

                                = 1.143 x 10^8

Written in scientific notation, the total number of pet dogs, cats, and birds is 1.143 x 10^8.

question c = They are the same. If you convert the number in standard form from question 1 to scientific notation, it is the same as the number in scientific notation found in question 2.

The Scientific Notation

Dogs: 6.99 x [tex]10^8[/tex]

Cats: 3.61 x [tex]10^8[/tex]

Birds:0.083  x [tex]10^8[/tex]

Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Also, the numbers in the millions place after the decimal required to be represented in a simpler format. As a result, representing a few integers in their expanded form is challenging. As a result, we employ scientific notation.

Given:

We have to change the number in  Scientific Notation in which only one significant number will be before the decimal and remaindering raise to power of 10.

First, Dogs: 69,900,000 whose Scientific Notation is

= 6.99 x [tex]10^8[/tex]

Second, Cats: 36,100,000 whose Scientific Notation is

= 3.61 x [tex]10^8[/tex]

Third, Birds: 8,300,000 whose Scientific Notation is

= 8.3 x [tex]10^6[/tex]

= 0.083  x [tex]10^8[/tex]
