A. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 3. The solution to system B will be the same as the solution to system A.
B. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -6. The solution to system B will not be the same as the solution to system A.
C. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -5. The solution to system B will not be the same as the solution to system A.

Answer: A. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
System A :
-x - 2y = 7 ..........(1)
5x - 6y = -3 ..........(2)
If we multiply the first equation by 5, then we will get :
5(- x - 2y) = 5(7)
⇒ - 5x - 10y = 35 ........... (3)
Now the Sum of equation (2) and equation (3) is:
⇒ Sum :
Now if we replace the second equation in system A with this , then we will get the system B.
Solution of system B:
First we will take the second equation as there is only one variable 'y'. So, we will solve that equation for 'y'
Now for solving 'x', we will plug y= -2 into the first equation
So, the solution of system B is (-3, -2), that means the solution of both systems are same.
Step-by-step explanation:
Answer: D:
To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.

23.82600 round to three significant figures
Answers
Answer:
23.8 i think
Step-by-step explanation:
Answer:
[tex]23.83[/tex]
Step-by-step explanation:
[tex]--------------------------------------------[/tex]
According to Maths3000, Rounding to 3 significant figures is probably the most common way of rounding off. Rounding the number off to 3 significant figures means you require 3 non-zero digits from the start of the number. So in example 1, 27.1258 gets rounded to 27.1 figures.[tex]--------------------------------------------[/tex]
It is 23.83 because rounding by three significant figures is picking three of the last numbers, and rounding the 4th number. In this case, 6 is more than 5, so 23.82 becomes 23.83

Sophie and Marcos are each saving for new bicycles. So far,
Sophie has $10 saved and can earn $5 per hour walking
dogs. Marcos has $4 saved and can earn $8 per hour at his
family’s nursery.
a. Write an equation for each individual.
b. After how many hours of work will Sophie and Marcos
have saved the same amount?
c. What will that amount be?
Answers
a. Sophie's equation: 10+5a=b
Marcos' equation: 4+8a=b
a=number of hours b=total needed for bike
b. a=2 for their totals to be the same.
c. b=20 for their totals to be the same.

Answers
Then, I would subtract the second row from the first row to make 7y=-70
Next, divide both sides by 7 to solve for y. y = -10.
2) To eliminate the y-terms, I would multiply the first equation by 2 and the second equation by -3. It will make 4x-6y=42 and 18x-6y=-21.
Now, subtract the two equations to make -14x=63.
Lastly, divide both sides of the equation by -14 to find x. x = -9/2
3) The answer as an ordered pair is (-9/2, -10).

Answers
Answer:
The answer is c.29
Step-by-step explanation:
I used Google xD
Answer:
Largest number = 29
Step-by-step explanation:
Let the consecutive numbers by (x + 1) ; (x + 2) and (x +3)
x +1 + x + 2 + x + 3 = 84 {Combine like terms}
x + x +x + 1 + 2 + 3 = 84
3x + 6 = 84
3x = 84 - 6
3x = 78
x = 78/3
x = 26
Largest number = x + 3 = 26 + 3
=29

First, choose the appropriate form. Then, fill in the blanks with the
numbers 63, 9, and 198. Let w represent the number of weeks.
Answers
Answer:
Jina will have enough money to buy the bike in 15 weeks
Step-by-step explanation:
y = mx + b
198 = 9x + 63
Subtract 63 from both sides;
135 = 9x
Divide both sides by 9;
x = 15
