(the second answer)
Step-by-step explanation:
So basically the x is going to be the first thing mentioned, so roses, which are 3$. 3x. Carnations are going to he 2nd and so therefore represented by Y. 2y.
3x + 2y (you're adding them)

In the equation 4x + 5 = 21, what does x =
Answer:
X=4
Step-by-step explanation:
In the equation, you have to subtract 5 from both sides.
4x + 5 = 21
-5 -5
4x=16
Then you gotta get rid of the X so divide the 4 from both sides. That gets you X=4
Answer:
x=4
Step-by-step explanation:

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

Step-by-step explanation:
If you look at Desmos you will see that when you put in the (x,y) coordinates in the x,y positions in your inequality that lines your plot and the shaded areas are different. If you put in each of the coordinates in the inequality you will see all the differenences between the shaded and the lines. I would do that in Desmos and you should be able to figure it out.

50=5x−3−8x−7
what is X?
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

Answer = (1.5, 0.25)
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.
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

12) It takes Kendra 12 minutes to drive 6 1/3 kilometers. How many kilometers does Kendra drive per minute? SHOW YOUR WORK. A) 2 B)19/36 C)1/6 D) 2 1/3
Answer:
36/19
Step-by-step explanation:
So to find this answer you have to divide 12 by 6 1/3. To figure that out I first turned 6 1/3 into an improper fraction (19/3) and then I put 12 over 1. To divide a fraction you have to multiply the dividend by the divisors reciprocal in this case 12/1 x 3/19 which equals 36/19 or 1 and 17/19

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:

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

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?
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%
