Answer:
Santosh purchased 4 new and 4 used DVDs.
Step-by-step explanation:
From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:
15x+5y=80, where:
x refers to the number of new DVDs
y refers to the number of used DVDs
Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:
15x+5x=80
20x=80
x=80/20
x=4
According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Answer:
20in²
Step-by-step explanation:
The area of a triangle is calculated using the formula A = bh/2
"A" means area.
"b" is for the base.
"h" is for the height.
It does not matter which is the base and which is the height, as long as they are perpendicular (at 90°) to each other.
5in can be the height.
8in can be the base.
Put the base and height measurements into the formula.
A = bh/2
A = (8in)(5in)/2 Multiply the measurements and the units.
A = (40in²)/2 Divide by 2
A = 20in² Area of the triangle
When you multiply units, in X in becomes in².
"in" has the exponents 1. When you multiply two "in" with exponent 1, you add the exponents. 1 + 2 = 2.
in¹ X in¹ = in¹⁺¹ = in²
