Answer:

w = -8

Step-by-step explanation:

7(w + 13) = 35

Divide each side by 7

7/7(w + 13) = 35/7

w+13 = 5

Subtract 13 from each side

w+13-13 =5-13

w = -8

Or you can distribute

7w +91 = 35

Subtract 91 from each side

7w+91-91 = 35-91

7w = -56

Divide each side by 7

7w/7 = -56/7

w = -8

Answer:

7(w+13)=35  {Here, 7 is wholly multiplied to w and 13}

7w+91=35

7w=35-91= -56

w= \(\frac{-56}{7}\)

w= -8

Proof:

7(-8+13)= -56+91= 35

Therefore, w= -8

Answer:

1:x=10

Step-by-step explanation:

Step 1: Add 5 to both sides.

2/5x-5+5+-1+5

2/5x=4

Step 2: Multiply both sides by 5/2.

(5/2)*(2/5x)=(5/2)*(4)

x=10

Answer: 84%

Step-by-step explanation:

A percentage is really a fraction with the denominator of 100. That means we can take the fraction of the students that went to the field trip (21/25) and make the denominator to 100. Since 25x4 is 100 we can do that but we also must do 21x4 because what you do to the top of the fraction you must do to the bottom. So you'd get 84/100 which is 84%

\(\frac{21}{25}\) ×\(\frac{4}{4} =\frac{84}{100}\)

Answer:

15 is the measure of B

Step-by-step explanation:

Complementary angles have a sum of 90 degrees

Hi

The aim of an equation is  to have  the letter on one side and a value to the pther side of the equal sign.  

For achieving this goal, I can use all operation I know and all quantities I want as long as I do it to each side in the same time. I will make apparent operation in bold.

So :  

2r - 5/4 = 58

if I want 2r  to be alone,  I need to get rid  of  -5/4  

The best way to do that is to add  5/4 to each side as  -5/4 + 5/4 = 0

so

2r -5/4 +5/4  = 58 +5/4

2r +0  = 58 +5/4

now we have :  

2r = 58+5/4

I will caculate the value of  58 +5/4

best way to do that is to convert 58 into  a  fraction .  as 58 *4 = 232  so  58 = 232/4

so now  we  have  :

2r = 232/4 +5/4

2r =  237/4

2r = 59.25

Now we have " 2r " , but my  aim is to have only one " r" .  So we  divide by "2" on each side :

2r /2  =  59.25 /2

r =29.625

If I want to check my result, I exchange the letter by the value I found.  

2 ( 29.625 )  - 5/4 =   59.25 - 5/4  =  59.25 - 1.25 =  58

as 58 is  the value given in line one for   2r - 5/4  , so my result is correct.

Answer:

r = 118.5

Explanation:

Given expression:

\(\sf \dfrac{2r-5}{4} = 58\)

Multiply Both sides by 4

\(\sf \dfrac{2r-5}{4} \times 4 = 58\times 4\)

Doing so gives:

\(\sf 2r-5 = 232\)

Add 5 on both sides

\(\sf 2r-5+5 = 232 + 5\)

Simplify following

\(\sf 2r = 237\)

Dividing Both sides by 2

\(\sf r = 118.5\)

Step-by-step explanation:

an acute angle is less then 90 degrees, a right angle is 90 degrees, an obtuse angle is more than 90 degrees, a straight angle is 180 degrees, and a reflex angle is more than 180 degrees but less then 360 degrees

Answer:

one half

Step-by-step explanation:

Total number of outcomes = 2

Event of obtaining green = 1

Probability of obtaining green= one half

The solution is Option B.

The probability of getting green P ( green ) = 1/2

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability of getting a green while tossing a coin be P ( green )

Now , the total number of colors in the coin = { red , green } = 2

The probability of getting a green = green / total number of colors in the coin

Substituting the values in the equation , we get

Probability of getting a green while tossing a coin P ( green ) = 1/2

Probability of getting a green while tossing a coin P ( green ) = 0.5

Therefore , the value of P ( green ) is 1/2

Hence . the probability is 1/2

Answer: -36 feet

Step-by-step explanation:

Step-by-step explanation:2,4

Answer:

Step-by-step explanation:

#18 complementary

3x +45 = 90

3x + 45-45 = 90 -45

3x = 45

Divide both sides by 3

3x/3 = 45/3

x = 15

#20 supplementary

2x + 3x + 25 = 180

5x + 25 = 180

5x + 25 - 25 = 180 -25

5x = 155

Divide both sides by 5

5x/5 = 155/5

x = 31

#15 - vertical

4x - 25 = 75

4x - 25 + 25 = 75 + 25

4x = 100

Divide both sides by 4

4x/4 = 100/4

x = 25

#16 - complementary

4x + 2x = 90

6x = 90

divide by 6 each side

x = 15

#19 complementary

x -20 + x = 90

2x -20 = 90

2x -20 + 20 =90 +20

2x = 110

Divide both sides by 2

2x / 2 = 110/2

x = 55

Answer: Below

Step-by-step explanation: Xenophon, an ancient Greek historian, philosopher, and soldier, often referred to historical events and institutions without providing detailed explanations. In order to identify the Council of the Ephori and its purpose, we can consult reference works and consider the available evidence.

The Council of the Ephori, also known as the Ephors, was a prominent institution in the city-state of Sparta during the classical period of ancient Greece. They played a crucial role in the Spartan government and were responsible for various administrative, judicial, and executive functions.

The Ephorate was established as part of the Spartan governmental system, which was characterized by a mixed constitution that included elements of monarchy, oligarchy, and democracy. The Council of the Ephori was an integral part of the oligarchic aspect of the Spartan government.

The primary purpose of the Council of the Ephori was to act as a check on the power of the two Spartan kings. Sparta had two hereditary kings who shared the executive authority, but the Ephors were elected annually and had the power to oversee and regulate the kings' actions. They had the authority to monitor the kings' conduct, judge their adherence to Spartan laws and customs, and even depose them if necessary.

Additionally, the Ephors had significant administrative responsibilities. They supervised the education of Spartan youth, oversaw the training of the military, and managed various public affairs. They were involved in the collection and distribution of state revenue, the implementation of laws, and the administration of justice.

The Council of the Ephori consisted of five members, who were elected by the Spartan citizens. The selection process involved a combination of election and lot-drawing, ensuring a degree of democratic participation. The Ephors held considerable power and influence within the Spartan society, and their role as a check on the kings helped maintain the stability and balance of power in the Spartan government.

In Xenophon's writings, he often mentioned the Council of the Ephori in the context of Spartan political affairs and decision-making. While he assumed his readers were familiar with the institution, he rarely provided explicit explanations. This approach was common in ancient Greek historical works, as they were often written for an audience that already possessed a certain level of knowledge about Greek institutions and customs.

To better understand the Council of the Ephori and its significance, one can consult ancient Greek historians like Herodotus, Thucydides, and Plutarch, who provide more detailed accounts of Spartan political institutions and the role of the Ephors within them.

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Answer:

  $3785.53

Step-by-step explanation:

You want the interest amount due at the end of 8 years on a $5000 loan at 7.3% compounded annually.

The amount due is multiplied by (1 +0.073) each year. After 8 years, the amount due will be ...

  5000(1.073^8) ≈ 8785.53

Of that, 5000 is the principal amount, so the remainder is interest.

  interest = $8785.53 -5000

  interest = $3785.53

Becky will have to pay $3785.53 in interest.
