I'm not sure
Step-by-step explanation:
-7-w<10
Add 7 to each side
-w<17
Change signs and flip sign
w>17
Hope this helps :)
A number=x
2x/6=42
2x=252 by multiplying both sides by 6
x=126 by dividing both sides by 2 to isolate the variable
Phone card = $20
You need to minus 17.92 from 20 = $2.08
$2.08 / 0.13 = how many minutes
= 16
