Answer:

constant of proportionality

Step-by-step explanation:

Assuming that we have two proportional quantities; one is x and one is y.

If we know whether the relationship between them is direct or inverse proportion, then the ratio of the two quantities y/x gives us a constant generally known as the constant of proportionality.

Step-by-step explanation:

2(5x-7) + 2(3x+2) = 70

x = 5

5(5)-7=  18

3(5) + 2 = 17

Answer:

Step-by-step explanation:

we have a rectangle, and the perimeter P=70

P=2L+2W

P=2(5x-7)+2(3x+2)=10x-14+6x+4=16x-10

16x-10=70

16x=70+10=80

16x=80

x=5

L=25-7=18

w=15+2=17

Answer:

7/20 of the lawn still needs to be mowed.

The son mowed most of the lawn 7/20 of the lawn still needs to be mowed.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Mrs. jones mowed 2/5 of her lawn and her son mowed 1/4 of it.

Now, Size of the lawn mowed by Miss Jones = 1/4

And, Size of the lawn mowed by her son = 2/5

To know who mowed the most lawn, find the LCM of the denominators.

The LCM of 4 and 5 = 20

Make the denominators of both fractions to be 20

Hence, Size of the lawn mowed by Miss Jones = 1/4 x 5/5 = 5/20

And, Size of the lawn mowed by her son = 2/5 x 4/4 = 8/20

Since, 8/20 > 5/20, Miss Jones son mowed more part of the lawn than Miss Jones.

Hence, The part of the lawn still needs to be mowed is,

⇒ 1 - 1/4 - 2/5

⇒ 7/20

Answer:

Options (2), (4) and (6)

Step-by-step explanation:

Option (1)

[tex]8^{-1}=\frac{1}{8}[/tex]

Not equivalent to [tex]\frac{1}{81}[/tex].

False.

Option (2)

[tex]9^{-2}=\frac{1}{9^2}[/tex]

      [tex]=\frac{1}{81}[/tex]

True.

Option (3)

[tex]\frac{9^{8}}{9^{4}}=9^{(8-4)}[/tex]

    [tex]=9^{4}[/tex]

    = 6561

False.

Option (4)

[tex]\frac{9^8}{9^{10}}=9^{8-10}[/tex]

     [tex]=9^{-2}[/tex]

     [tex]=\frac{1}{81}[/tex]

True.

Option (5)

[tex]9^{-6}9^{3}[/tex] = [tex]9^{-6+3}[/tex]

         = [tex]9^{-3}[/tex]

         = [tex]\frac{1}{9^3}[/tex]

         = [tex]\frac{1}{729}[/tex]

False

Option (6)

[tex]9^{5}9^{-7}=9^{(5-7)}}[/tex]

          [tex]=9^{-2}[/tex]

          [tex]=\frac{1}{9^2}[/tex]

           [tex]=\frac{1}{81}[/tex]

True.

Therefore, Options (2), (4) and (6) are the correct options.

Applying the negative exponent rule of power, the expressions that are equivalent to the given expression, 1/81, are: B, D, and F.

The negative exponent rule states that: [tex]a^{-n} = \frac{1}{a^n}[/tex].

Thus, given the expression, 1/81, it can be rewritten or simplified as follows:

1/81 = [tex]81^{-1} = 9^{-2}[/tex] = [tex]\frac{9^8}{9^{10}}[/tex] = [tex]9^5 \times 9^{-7}[/tex]

The expressions that will be equivalent to 1/81 can be expressed, based on the negative exponent rule of power, as:

[tex]9^{-2}, \frac{9^8}{9^{10}} , 9^5 \times 9^{-7}[/tex] (option B, D, and F).

Step-by-step explanation:

How many more votes the winner received than the loser can be thought of as the distance between the two numbers of votes on the number line.

Hint #22 / 5

The distance between two numbers is equal to the absolute value of their difference.

For example, | a - b|∣a−b∣vertical bar, a, minus, b, vertical bar is the distance between aaa and bbb.

Hint #33 / 5

We want to find the distance between \blue{w}wstart color #6495ed, w, end color #6495ed and \pink{v}vstart color #ff00af, v, end color #ff00af.

Hint #44 / 5

The distance between \blue{w}wstart color #6495ed, w, end color #6495ed and \pink{v}vstart color #ff00af, v, end color #ff00af is |\blue{w} - \pink{v}|∣w−v∣vertical bar, start color #6495ed, w, end color #6495ed, minus, start color #ff00af, v, end color #ff00af, vertical bar or |\pink{v}-\blue{w}|∣v−w∣vertical bar, start color #ff00af, v, end color #ff00af, minus, start color #6495ed, w, end color #6495ed, vertical bar.

Hint #55 / 5

\left\lvert \blue w- \pink v\right\rvert∣w−v∣open vertical bar, start color #6495ed, w, end color #6495ed, minus, start color #ff00af, v, end color #ff00af, close vertical bar always represents how many more votes the winner received than the loser.

The expressions that always represents how many more votes the winner received than the loser will be Choice b .∣w−v∣

Cicero and Themistocles run for the same political office. Cicero received www votes in the election and Themistocles received vvv votes.

This can be thought of as the distance between the two numbers of votes on the number line.

Here, The distance between two numbers is equal to the absolute value of their difference.

For example; | a - b| vertical bar, a, minus, b, vertical bar is the distance between aaa and bbb.

Substitute the first value from the parentheses for x, and the second value for y in the equation.

Calculate.

If the answer is true, the point is a solution on the line.

3(2) -5(1) = 1

6 –5 = 1

1 = 1. True. point B is a solution on the line.

D* for example:

Answer:

160

Step-by-step explanation:

First, lets assign a varible x. Let x be the number where 75% of x is 120. Next, we can convert the words of the problem into an equation. Now we have, 75% * x = 120 = 0.75x = 120. By multiplying both sides by 100, we get, 75x = 12000. So, x = 160.
