Answers

Answer 1

Answer:

2.73     8.75

Step-by-step explanation:

n = 1  

1 (DOUBLE) = 1+1 = 2  

2 +3/4 = 1.5

1.5 +2 = 3.5  

3.5 x 0.22 = 0.77

3.5 - 0.77 = 2.73

n = 1

1 + 3/4 = 1 + 0.75 = 1.75

1.75 (DOUBLE) = 3.5

3.5 x 2 1/2 = 8.75

Answer 2
2.72 8.75 good luck :)))

Describe two ways the Distributive Property can be used to write equivalent expressions.

Answers

For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

The two ways for the Distributive Property can be used to write equivalent expressions is explained below:

Distributive Property:Here we apply the distributive property to the expression 3 (2 + x) to generate the equivalent expression 6 + 3x.Now apply the distributive property to the expression 24x + 18y to generate the equivalent expression 6 (4x + 3y)

Answers

Answer: 160 songs.

75% hip hop music   -    120 songs

100% all music          -     x songs

Let's write the proportion:

[tex]\dfrac{120}{75} =\dfrac{x}{100} \\\\75x=120 \cdot 100\\75x=12000\\75x : 75 = 12000 : 75\\x = 160[/tex]

Thus, Landon have 160 songs in his music library.
