Answer: B
<u>Step-by-step explanation:</u>
2x - 3y = -7 → 2(2x - 3y = -7) → 4x - 6y = -14
-4x + 6y = -10 → 1(-4x + 6y = -10) → <u>-4x + 6y</u> = <u>-10 </u>
0 = -24
FALSE
Since this makes a false statement, there are no solutions
a). 0.45 with a line over the 45 means 0.45454545454545... forever.
It's equivalent to 45/99 which is <em>5/11</em> .
b). 0.45 with a line over the 5 means 0.455555555... forever.
It's equivalent to (0.4 + 0.555555.../10)
The 0.4 part is 4/10
The 0.5555555555.../10 part is 5/90 .
(4/10) + (5/90) = <em>41/90 </em>
c). 0.45 means 45/100 . That's <em> 9/20</em> .
