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 work is on the picture attached, but a = 1
Hope this helps!!
The formula for perimeter is:
<span>P = 2 h + 2 w</span>
where P is perimeter = 120 cm, h is height, w is width
we are also given that: h = (2/3) w, therefore:
P = 2 (2/3) w + 2 w = 120
(4/3) w + 2 w = 120
w = 36 cm
Therefore l is:
l = (2/3) w = 24 cm
<span>Hence the dimension should be 24cm by 36 cm</span>
