Claire said that 10/15 of her CDs are country music. Which statement could be true based upon this relationship?
never [62]

Answer:

C. Claire has 10 country CDs and 5 Jazz CDs

Step-by-step explanation:

\dfrac{10}{15} means that 10 out of 15. So we can assume that in total she has 15 CDs and 10 of them are Country and the other is Jazz.

This would rule out choice D.

If we reduce this fraction then we would have:

\dfrac{10}{15} = \dfrac{2}{3}

This means that two-thirds of her CDs are country music. So this would rule out A and B choices.

Now C is correct because 10 country plus 5 Jazz is equal to 15 CDs. So we have the correct total.

The answer is C.

Which of the following describes the sum in terms of p and q?(1 point)
snow_tiger [21]

The description of the summation expression given as p + (-q) is the sum, p + (-q), is the number located a distance, |p|, from , q, in the negative direction.

<h3>How to describe the sum in terms of p and q?</h3>

The summation expression is given as:

p + (-q)

In the above summation expression, we assume that:

p ⇒ Positive number

- q ⇒ Negative number

Having said that:

The expression -q would go in the negative direction if plotted on a number line

This means that the description of the summation expression given as p + (-q) is the sum, p + (-q), is the number located a distance, |p|, from , q, in the negative direction.

Hence, the description of the summation expression given as p + (-q) is the sum, p + (-q), is the number located a distance, |p|, from , q, in the negative direction.

Which ordered pair would form a proportional relationship with the point graphed below?
vampirchik [111]

Hey there! I'm happy o help!

To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.

-10(-1/3)=3 1/3≠30

30(-1/3)=-10≠-15

-30(-1/3)=10

80(-1/3)=-26 2/3≠-30

Therefore, the correct answer is (-30,10).

Have a wonderful day! :D
