Answer:

The cost for 5 songs is $5.35

Step-by-step explanation:

Find the unit rate for 1 song by dividing the total cost for 3 songs by 3

$3.21 ÷ 3 = $1.07

The unit rate is $1.07 per song, so multiply that by 5 to find the total cost for 5 songs

$1.07 * 5 = $5.35

Isandro and Yvette each have a calculator. Yvette starts at 100 and subtracts 7 each time. Isandro starts at 0 and adds 3 each t
Talja [164]

Answer: <u>30</u>

Step-by-step explanation:

Yvette- <em>100-7</em>

Isandro- <em>0+3</em>

1.) I'm going to speed up the process and multiply by 5.

Yvette: <em>100-7</em>

7  × 5 = 35

100-35= 65

65-35= 30

Isandro: <em>0+3 </em>

3 × 5 = 15

0+15= 15

15+15=<em> </em>30

2.) If they keep going on this pattern they will have the same number on the 10 round.

Simplify completely 8x^3 ÷ 6x^2 - 4x / -2x
artcher [175]

Answer:

Simplified form is -(\frac{8x^{3}}{3x-2}).

Step-by-step explanation:

The given expression is 8x^{3}\div \frac{6x^{2}-4x}{-2x}

We can rewrite the given expression as = 8x^{3}\times (-\frac{2x}{{6x^{2}-4x}})

Further simplification of the expression gives =\frac{-16x^{4}}{6x^{2}-4x}

=\frac{-16x^{4}}{2x(3x-2)}

=-(\frac{8x^{3}}{3x-2})

So the simplified of the given expression is =[tex]-(\frac{8x^{3}}{3x-2})

What percent of 72 is 9? 1/8% 1 1/4% 12 1/2% 125%
USPshnik [31]

Answer:

12\dfrac 12\%

Step by step explanation:

\text{Let it be}~ x\%,\\\\~~~~~72 \cdot x \% = 9\\\\\\\implies 72\cdot \dfrac{x}{100} = 9\\\\\\\implies x = \dfrac{9 \times 100}{72}\\\\\\\implies x = \dfrac{100}{8}\\\\\\\implies x = \dfrac{25}2\\\\\\\implies x = 12 \dfrac 12\\\\\\\text{Hence 9 is}~ 12\dfrac 12\% ~ \text{of}~ 72
