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 .

16a2-400b2
factorize the expression
Answer:
[tex]16(a + 5b)(a - 5b)[/tex]
Step-by-step explanation:
[tex]16 {a}^{2} - 400 {b}^{2} [/tex]
[tex] = > {(4a)}^{2} - {(20b)}^{2} [/tex]
[tex] = > (4a + 20b)(4a - 20b)[/tex]
Taking 4 common from each expression gives,
[tex] = > 4(a + 5b) \times 4(a - 5b)[/tex]
[tex] = > 16(a + 5b)(a - 5b)[/tex]
*NEED HELP NOW MATH HOMEWORK* Use the distributive property to simplify the expression. The expression is 8(5+w) simplify it please!!!
Answer:
40+8w
Step-by-step explanation:
Heya! When it comes to using the distributive property, you multiply the numbers inside the parenthesis with the outside number. In that case, 5 and 8 gives you a product of 40, and 8 and w give you a product of 8w. I hope this helped! <3 (Please mark as brainliest if I got this right!)
Answer:
40+8w
Step-by-step explanation:

.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

What is the square root of 160
Answer:
The square root is 12.649.....
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.
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:bbbbb
Step-by-step explanation:
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.
I hope this helps!! Have a wonderful day!!! :D

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]
A resistor utilized in a critical electronic component is required to have a resistance of 45 ohms /- 0.32 ohms. The current manufacturer of this resistor has found that its manufacturing process produces a mean value of 50 ohms and has a standard deviation of 0.16 ohms. What would be the C P of this process
Answer:
The value is [tex]CP = 0.667[/tex]
Step-by-step explanation:
From the question we are told that
The resistance is [tex]R = 45 \pm 0.32\ \Omega[/tex]
The mean is [tex]\mu = 50 \Omega[/tex]
The standard deviation is [tex]\sigma = 0.16 \Omega[/tex]
Generally the upper limit of the resistance specified in the question(i.e upper specification limit (USL )) is
[tex]USL = 45 + 0.32 = 45.32 \ \Omega[/tex]
Generally the lower limit of the resistance specified in the question(i.e lower specification limit (USL )) is
[tex]LSL = 45 - 0.32 = 44.68 \ \Omega[/tex]
Generally the CP of the process of manufacturing the resistor is mathematically represented as
[tex]C P = \frac{ USL - LSL }{ 6 * \sigma }[/tex]
=> [tex]CP = \frac{45.32 - 44.68 }{6 * 0.16}[/tex]
=> [tex]CP = \frac{0.64 }{0.96}[/tex]
=> [tex]CP = 0.667[/tex]

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.

Answer:
It would be option two: Bill's Electric Company charges 6 dollars per hour plus a flat rate of 15 dollars for a service call. If Monica has at least 100 dollars to spend, how many hours can the service man work?
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.

Please find x ASAP!...........
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°
Which ordered pair is a solution of the equation? 3x + 3y = -x + 5y
Answer:
Undefined
Step-by-step explanation:
Without option choices, I don't know what the answer could potentially be.
I got X=.5y, and while solving for Y, I came up with 4.5y=4.5y
It has been a few years since I have done this, but I believe the answer is undefined.
