You buy 70 of your favorite songs from a Web site that charges $0.98 for each song. What is the cost of 70 songs? Use mental math.
To find the cost of 70 songs, you can multiply the cost per song, which is $0.98, by the number of songs, which is 70:
$0.98 * 70 = $68.60
So, the cost of 70 songs would be $68.60.
Write an expression in simplified form for the area of the rectangle.
8
5x+2
The expression for the area of the rectangle is given by multiplying the length and width of the rectangle. In this case, the length is 8 and the width is 5x + 2. So, the expression in simplified form for the area of the rectangle is:
Area = 8 * (5x + 2) = 40x + 16
Write an expression in simplified form for the area of the rectangle.
10
3x+5
The expression for the area of the rectangle is given by multiplying the length and width of the rectangle. In this case, the length is 10 and the width is 3x + 5. So, the expression in simplified form for the area of the rectangle is:
Area = 10 * (3x + 5) = 30x + 50

Based on the given number, 20/10, we can determine its classification as follows:
Natural numbers: Natural numbers are positive whole numbers, starting from 1. Since 20/10 is not a positive whole number, it is not a natural number.
Whole numbers: Whole numbers are non-negative integers, including 0. Since 20/10 is not an integer, it is not a whole number.
Integers: Integers include positive and negative whole numbers, including 0. Since 20/10 is not an integer, it is not an integer.
Rational numbers: Rational numbers can be expressed as a ratio of two integers, where the denominator is not zero. Given that 20/10 is a ratio of two integers (20 and 10), it is a rational number.
Irrational numbers: Irrational numbers cannot be expressed as a fraction or ratio and cannot be written as a terminating or repeating decimal. As 20/10 can be expressed as a fraction and simplifies to the rational number 2, it is not an irrational number.
Real numbers: Real numbers include rational and irrational numbers. Since 20/10 is a rational number, it is also a real number.
In summary, the given number 20/10 belongs to the following sets:
Natural: No
Whole: No
Integers: No
Rational: Yes
Irrational: No
Real: Yes
