choose the equivalent system of linear equations that will produce the same solution as the one given below. (1 point)
6x + 2y = −6
3x − 4y = −18
select one:
a. 12x + 4y = −12
15x = −30
b. 8x + 4y = −4
14x = −10
c. 6x − 8y = −36
−6y = −42
d. 6x − y = −15
3y = 9

Answer choice a.

Step-by-step explanation:

Let's do part of the work of solving the given system:

6x + 2y = −6

3x − 4y = −18

Multiply the first equation by 2 so as to make the coefficient of y = to 4:

12x + 4y = -12

Combine this result with the second equation:

12x + 4y = -12

3x − 4y = −18

 15x = -30

Note that these results are precisely the same as the equations in Answer Choice a.

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
