The width is 8.2
Perimeter = 2W + 2L (there are four sides of a rectangle, two longer sides, two shorter, W and L) 

<span>65.6 = 2W + 2L 
</span><span>L = 3W so substitute 3W in for L </span>
<span>65.6 = 2W +2 (3W) </span>
<span>65.6 = 8W </span>
<span>W = 8.2 cm </span>
<span>L = 3(8.2) </span>
<span>L = 24.6cm </span>

3w=l
2l+2w=65.6
8w=65.6
w=8.2
l=24.6

Gary had a 40% discount for car speakers. The sale price of the speakers was $96.25. What was the original price of the speakers
Ostrovityanka [42]

Answer:

Step-by-step explanation:

If the price after the discount is subtracted is $96.25 then this is what you do

u times 0.40 x 96.25 which is 38.5 so since you are wanting to know what the price was before the discount you would add 38.5 to 96.25 and when you do that your answer is 134.75

but if you are just trying to get the discount from 96.25 you subtract 38.5 from 96.25
