Answer: Infinitely many solutions.
Step-by-step explanation:
When looking at the system, it is immediately clear that the second equation is simply the first equation with all terms multiplied by 2. Therefore, there are infinite solutions because these are actually the same exact line when graphed and will always equal each other no matter what the values for x and y are.
Select the correct answer.
A system of equations and its solution are given below.
System A
To get system B below, the second equation in system A was replaced by the sum of that equation and the first equation in system A multiplied by -2.
System B
A.
The second equation in system B is 7x = 30. The solution to system B will be the same as the solution to system A.
B.
The second equation in system B is -7x = 14. The solution to system B will be the same as the solution to system A.
C.
The second equation in system B is -7x = 14. The solution to system B will not be the same as the solution to system A.
D.
The second equation in system B is 7x = 30. The solution to system B will not be the same as the solution to system A.

The distance between Columbia and Savannah is 6.5 inches on a map. If the map scale is 1 inch = 30 miles, what is the actual distance between the towns?
Answer:
195 miles
Step-by-step explanation:
Because if 1 inch= 30 miles you would have to multiply 30 by 6 because there is 6 inches, which is 180. The you have to look at the .5. .5 is half an inch, so you have to divide 30 by 2. you get 15 and then add 15 to the 180 and get 195.

A bag contains 4 yellow tiles and 2 green tiles . A tile will be taken from the bag at random and set aside. A second tile will then be taken from the bag at random . What is the probability that both tiles will be green?
There is a 40 percent chance because there are more yellow tiles than green
Answer:1/15
Step-by-step explanation:
In total there are 6 marbles. 2 out of 6 are green so it'll be 2/6 green marbles. If one is taken away and put aside with no replacement, then it'll be 1/5. (1 out of the 5 marbles left) Then you'll multiply 2/6 and 1/5 and you'll get 1/15.

.The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel?
Answer:
1271.7in
Step-by-step explanation:
A complete rotation is = circumference of the wheel.
So calculate the circumference which is pi times diameter.
27 times pi (which is 3.14) = 84.78in one rotation
so if you make 15 rotations, you are multiplying it by 15
15 x 84.78 = 1271.7in

A 2018 Chevrolet Suburban averages 15 miles per gallon of gas in the city. It drives 47% farther per gallon of gas on the highway. If gas costs $3.25 per gallon, how much does a Suburban cost to drive per mile on the highway
Answer:
On the highway, the cost to drive per mile is $2.21
Step-by-step explanation:
In the city the average distance per gallon is 15 miles
On the highway, he can drive 47% farther;
The distance he can cover on the highway per gallon will be;
15 + 47% of 15
= 15 + 0.47(15)
= 15 + 7.05 = 22.05
So on the highway, he can travel a distance of 22.05 miles
So the cost per mile on the highway would be;
$3.25 for 15 miles
$x for 22.05 miles
so we have the cost to drive per mile on the highway as;
(3.25 * 15)/22.05 = $2.21

Answer:
D) b + 6 = 17; b = 11
Step-by-step explanation:
Marco checked out a total of 17 items. It is given that 6 of them are movies. Set the equation. Let b = the amount of books checked out:
Whole = Part A + Part B
Whole = 17
Part A = movies = 6
Part B = books = b
17 = 6 + b
Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Subtract 6 from both sides:
17 (-6) = 6 (-6) + b
b = 17 - 6
b = 11
D) b + 6 = 17; b = 11 is your answer.

Which system of linear equations will have the same solution as that of the given system of linear equations
Answer:
Option 1 is correct.
Step-by-step explanation:
Given two linear equations to us are ,
[tex]\qquad 3x + 7y = 10 \\\\ \qquad x + y = 2 [/tex]
And we have to find which system of linear equations have same answer .
On considering option (1) which is ,
[tex]\qquad 3x + 7y = 10 \\\\ \qquad 2x + 2y = 4 [/tex]
On taking the second equation in this ,
[tex]=> 2x + 2y = 4 \\\\=> 2( x + y ) = 4 \\\\=> x+y =\dfrac{4}{2}}\\\\\boxed{\red{\bf => x + y = 2 } }[/tex]
This is same as the second one given in the Question . And the first one is already same .
Hence option (1) is correct .

Answer: C
Step-by-step explanation:
The missing side of the triangle is the hypotenuse. We are given the length for both legs. To find the midding leg, we need to use teh Pythagorean Theorem.
Pythagorean Theorem: a²+b²=c²
A and b are the legs, while c is the hypotenuse. We plug in the legs and solve for c.
2²+3.6²=c² [exponent]
4+12.96=c² [add]
16.96=c² [square root both sides]
[tex]c=\sqrt{16.96}[/tex]
Now that we have found the hypotenuse, we know the answer is C.
Hello!
[tex]\large\boxed{\sqrt{16.96}cm}[/tex]
Use the Pythagorean theorem to solve for the missing side of the triangle:
a² + b² = c²
Plug in the given side lengths to solve for "c", or the Hypotenuse:
(2)² + (3.6)² = c²
4 + 12.96 = c²
16.96 = c²
Take the square root of both sides:
√16.96 = c

Joyce says that 4 is a factor of every whole number that has a 4 in the ones place. Nathan says 2 is a factor of every whole number that has a 4 in the ones place. Are they both correct? Complete the following to explain. Joyce is correct For example, 14 has a 4 in the ones place and choose... 4. Choose... Nathan is Choose... Four is Choose... and all numbers with an number in the ones place have Choose... as a factor.
9514 1404 393
Answer:
Joyce is incorrect; 14 is not divisible by 4Nathan is correct; 4 is divisible by 2 and all numbers with 4 in the ones place have 2 as a factor.Step-by-step explanation:
We know that 4 is divisible by 4, and 14 is not. It has to do with 14 = 4 + 10, where 10 does not have 4 as a factor.
On the other hand, both 4 and 14 are divisible by 2. That's because 14 = 4 + 10, where 10 has 2 as a factor.
Joyce is incorrect; Nathan is correct—for the reasons shown above.

Answer:
x = 40°
Step-by-step explanation:
Both triangles can be regarded as similar triangles. Therefore, their corresponding angles would be congruent to each other.
Thus:
x = 180° - (75° + 65°)
x = 180 - 140
x = 40°
$300 bases price plus $20 per guest for up to 30 guests. Whats the initial value?
The base price is $300 and $20 per guest, then the initial value will be equal to $300.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data mentioned in the question,
Base price = $300
Price per guest = $20 for up to 30 guests.
Then, the equation according to this will be,
$300 + $20(x)
Here, x is the number of guest, which is not more than 30.
Also, the initial value will be equal to the base value, which is 300.

Sketch a plane region and indicate the axis about which it is revolved so that the resulting solid of revoltuion (found using the shell method) is given by the integral.
π
2π∫ xsinx dx
0
Answer:
See attached picture.
Step-by-step explanation:
The idea of the shell method is to find the volume of a differential shell by using the formula:
[tex]V=2\pi\int\limits^a_b {rh} \, dr[/tex]
in the drawing we can see that r=x, h=sin x and dr=dx. The area is revolving about the y-axis from x=0 to [tex]x=\pi[/tex]. So the volume is found by using the following integral:
[tex]V=2\pi\int\limits^\pi_0 {xsin x} \, dx [/tex]

Step-by-step explanation:
6 dollars an hour means it would be 6x.
A flat rate of 15 means there would be just 15 as a number, no x's.
And the sign is less than or equal to, so she has over a hundred dollars to spend.
