Answer:
25 and 480
Step-by-step explanation:
Let the length of second side be x" ,
So,
Length of first side = 2" shorter than second = ( x - 2 )"
Length of third side = 5" longer than second = ( x + 5 )"
=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=×=

Given, perimeter = 33"
= > first side + second side + third side = 33"
= > ( x - 2 ) + x + ( x + 5 ) = 33
= > x - 2 + x + x + 5 = 33
= > 3x + 3 = 33
= > 3x = 30

= > x = 10
Hence, length of each side is
First side = ( x - 2 )" = ( 10 - 2 )" = 8 inches
Second side = x " = 10 inches
Third side = ( x + 5 )" = ( 10 + 5 )" = 15 inches

Step-by-step explanation:
Answer: $90
Step-by-step explanation:
Let the original cost be represented by x
From the question, it was given that the cost of headphones at 40% discount is $36
Thus, 40% discount = $36
100% = x
Then, convert to decimal
40% = 40/100 = 0.4
100% = 100/100 = 1
Therefore, 0.4 = $36
1 = $x
0.4x = $36
Divide both sides by 0.4
x = $36/0.4
x= $90
Original cost of the headphone was $90.
I hope this helps.
