50=5x−3−8x−7
what is X?

Answers

Answer:

x = -20

Step-by-step explanation:

Solve for x:

50 = 5 x - 8 x - 7 - 3

Grouping like terms, 5 x - 8 x - 7 - 3 = (5 x - 8 x) + (-3 - 7):

50 = (5 x - 8 x) + (-3 - 7)

5 x - 8 x = -3 x:

50 = -3 x + (-3 - 7)

-3 - 7 = -10:

50 = -10 - 3 x

50 = -3 x - 10 is equivalent to -3 x - 10 = 50:

-3 x - 10 = 50

Add 10 to both sides:

(10 - 10) - 3 x = 10 + 50

10 - 10 = 0:

-3 x = 50 + 10

50 + 10 = 60:

-3 x = 60

Divide both sides of -3 x = 60 by -3:

(-3 x)/(-3) = 60/(-3)

(-3)/(-3) = 1:

x = 60/(-3)

The gcd of 60 and -3 is 3, so 60/(-3) = (3×20)/(3 (-1)) = 3/3×20/(-1) = 20/(-1):

x = 20/(-1)

Multiply numerator and denominator of 20/(-1) by -1:

Answer: x = -20

Answer:

x=-20

Step-by-step explanation:

Combine like terms and solve for x.

50= -3x-10

60= -3x

x=-20

Consider the graph showing two functions.
Which answer can be used to find the solution to the system of equations?

Answers

According to the graph, it is found that it represents the solution of the following system:

Option B [tex]x=\frac{9}{x}[/tex] is correct.

What are system of equations?

A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.

The equations in the system can be linear or non-linear.

In the graph, two equations intersect at [tex]x = -3[/tex] and at [tex]x = 3.[/tex]

One is a straight line, in which the x-coordinate is equals to the y-coordinate, thus it is the line [tex]y = x.[/tex]

The other is an exponential equation, that goes to 0 as x goes to infinity, so x is in the denominator. At [tex]x = -3, y = -3,[/tex] and at [tex]x = 3, y = -3.[/tex] Thus, the function that has this graph is [tex]\frac{9}{x}[/tex], which means that the correct option is:

B  [tex]x=\frac{9}{x}[/tex].

Forty-seven percent of fish in a river are catfish. Imagine scooping out a simple random sample of 25 fish from the river and observing the sample proportion of catfish. What is the standard deviation of the sampling distribution? Determine whether the 10% condition is met.

Answers

Question options:

The standard deviation is 0.0998. The 10% condition is not met because there are less than 250 fish in the river.

The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river.

The standard deviation is 0.9002. The 10% condition is met because it is very likely there are more than 250 fish in the river.

The standard deviation is 0.9002. The 10% condition is not met because there are less than 250 fish in the river.

We are unable to determine the standard deviation because we do not know the sample mean. The 10% condition is met because it is very likely there are more than 250 fish in the river

Answer:

The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 fish in the river

Explanation:

Formula to calculate standard deviation = √p(1-p)/n

Given p= population proportion

n= sample size

From the question,

We are given p(population proportion of catfish in the river)= 0.47

n(sample size of fish collected from river) = 25

The standard deviation using the formula above = √0.47(1-0.47)/25

= 0.0998

The 10% condition demands that a sample size be not less than 10% of the population

To check if the 10% condition was met, we know that a river will likely have up to 250 fish in it and so,

10% of 250= 0.10×250=25 fish

Therefore the option B chosen is correct

Answer:

Option D

Step-by-step explanation:

17). Area of a sector of a circle = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]

                                                  = [tex]\frac{\theta}{360}(\pi r^{2} )[/tex]

     Here 'r' = radius of the circle

     From the picture attached,

     r = 10 ft

     θ = 300°

    Area of the sector = [tex]\frac{300}{360}[\pi (10)^{2}][/tex]

                                    = [tex]\frac{5}{6}(100\pi )[/tex]

                                    = [tex]\frac{250\pi}{3}[/tex]

    Area of the sector = [tex]\frac{250\pi}{3}[/tex] ft²

   Therefore, Option (D) will be the correct option.

Answer:

WILL MARK BRAINLIEST!!!!!! Which of the following graphs represents a function?

Answers

Answer:

C

Step-by-step explanation:

Determine the solution for the equation, 5w - 9= 44.

Answers

Answer:

w=2

Step-by-step explanation:

Simplifying

4w + -9(6 + -5w) = 44

4w + (6 * -9 + -5w * -9) = 44

4w + (-54 + 45w) = 44

Reorder the terms:

-54 + 4w + 45w = 44

Combine like terms: 4w + 45w = 49w

-54 + 49w = 44

Solving

-54 + 49w = 44

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '54' to each side of the equation.

-54 + 54 + 49w = 44 + 54

Combine like terms: -54 + 54 = 0

0 + 49w = 44 + 54

49w = 44 + 54

Combine like terms: 44 + 54 = 98

49w = 98

Divide each side by '49'.

w = 2

Simplifying

w = 2

Answer:

w has multiple forms

exact w = 53/5

decimal w = 10.6

mixed number w = 10 3/5

5 x 53/5 - 9 = 44

On the first visit to the veterinarian's office, Cora's kitten weighed 550 grams. On the second visit, the kitten had gained 350 grams. On the third visit, the kitten had gained another 300 grams.
What is the percent increase since the first visit in the kitten’s weight rounded to the nearest percent?

Answers

Answer:

118%

Step-by-step explanation:

550 grams and 300+350 grams = 650 grams

650/550 grams x 100 = 118.18

So 118.18 % rounded is 118%

Hope this helps plz hit the crown :D

Answer:

The kitten has gained a 218% more weight since the first visit to the vet.

Step-by-step explanation:

In order to get the percentage the kitten has gained you have to add all the weight together and divide the first visit by the total weight.

TO find the total weight is found by adding all the weights together:

550 + 350 + 300 = 1200

now we divide 1200 by 550 to get a decimal which allows us to find the percentage:

1200 / 550 = 2.18181818182

now we multiply 0.45833333333 by 100 to turn the decimal to a percentage:

2.18181818182 * 100 = 218.181818182%

Now we round up to the nearest percentage which is:

218.181818182% = 218%
