We know that
• Lashonda purchased a prepaid phone card for $20.
,
• Long-distance calls cost 8 cents a minute.
,
• The remaining credit on her card is $17.12.
This problem can be expressed as

Where <em>x</em> is the number of minutes.
We solve the equation for <em>x</em>

Then, we divide by -0.08 the equation

<h2>Therefore, Lashonda's call last 36 minutes.</h2>
The perimeter for the rectangle is 64.5m.
To find area so l x w x h
Answer:
35
Step-by-step explanation:
70 × 0.5 = 35
or
50% = 1/2
so
70/2 = 35
The answer is x=-20.
6+ -28 -x =-2
You first add 28 to each side=6+-x=26 then you minus 6 from each side=-x=20.
Then you divide 20 by -x resulting in x=-20
