I think this is the answer huehue idk correct or not
Answer:
(Choice C) C Replace one equation with a multiple of itself
Step-by-step explanation:
Since system A has the equations
-3x + 12y = 15 and 7x - 10y = -2 and,
system B has the equations
-x + 4y = 5 and 7x - 10 y = -2.
To get system B from system A, we notice that equation -x + 4y = 5 is a multiple of -3x + 12y = 15 ⇒ 3(-x + 4y = 5) = (-3x + 12y = 15).
So, (-x + 4y = 5) = (1/3) × (-3x + 12y = 15)
So, we replace the first equation in system B by 1/3 the first equation in system A to obtain the first equation in system B.
So, choice C is the answer.
We replace one equation with a multiple of itself.
Y^a+b
The top right one. Hope this helps:)
Since there are 10 hundreds in every thousand, a 4 in the thousands place will represent a value 10 times greater than a 4 in the hundreds place.
The answer is 20.6 because 17+3=20 and then you add the decimal so 20+0.6= 20.6
