Hi there! Her mistake is in step 1.
She subtracted -25 by 25. -25 - 25 = -50
What she SHOULD have done was add 25 to each side. This obeys the property of reciprocals.
-25 + 25 = 0
Hope this helps.

2/3 + 1/2 is 7/6
Hope this helps!
I could be wrong because people do make mistakes, but i’m pretty sure the answer i got was right
$128.60
explanation:
$257.20 divided by 4=$64.30
$257.20-$64.30=$192.90
$192.90 divided by 3=$64.30
$192.90-$64.30=$128.60
therefore, she has $128.60 left from her paycheck after bills
Answer:
53,760,970 households/year
Step-by-step explanation:
First step is to do 65,929,420 - 12,168,450 = 53,760,970
Now divide 53,760,970 by 20 since the difference in 1997 and 1977 is 20
53,760,970/20 = 2,688,048.5
So each year 2,688,048.5 people got cable.
But it would be 53,760,970/year because then you could divide it by how ever many years to see how many people got cable.
Hope this helps!!
