If x+3y=-2 and 2x-6y=-8, which of the following equation is true?
rjkz [21]
Your answer is B) 12y = 4

You can find this by first rearranging the equation x + 3y = -2 to the form ‘x =‘:
x = -2 - 3y.

Then you can substitute this into the second equation, 2x - 6y = -8, and expand and solve:
2(-2 - 3y) - 6y = -8
-4 - 6y - 6y = -8
-12y = -4

Now because we know that -12y = -4, this is equivalent to 12y = 4, which is option B.

I hope this helps! Let me know if you have any questions :)

The following circle graph represents first-quarter absences of Washington Middle School students. If 96 students had two or mor
UkoKoshka [18]
How many students had 3 or more absences?  Add together {45%, 21%, 23%} and subtract that sum from 100%:  11%.

How many students had two or more absences?  Add together this 11% and 21%:  32% had two or more absences.  Let the total number of students be n.  Then 32% of these n students add up to 96 students.  Thus, 0.32n = 96, and n= 300.

How many students had one absence?  The chart shows that that is 45%, and we know that there are 300 students total.  

Thus, the number of students who had one absence was 0.45(300) = 135.
