Since there are 5 pens total, and three of those pens are blue, the probability for both pens being blue is 3/5.
(just like if the black pens were being chose the probability would be 2/5, since there are 5 pens total and 2 black pens.)<span />

Combine the like terms to create an equivalent expression: <br> 2s+(−4s)=?
Sergeeva-Olga [200]

Answer:

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Step-by-step explanation:

Considering the expression

2s+\left(-4s\right)

As we know that

  • Like terms are said to be the terms which hold the same variables raised to the same power.
  • For example, 3x and 2x are like terms as they contain the same variable x raised to the same power.

Lets solve the expression

2s+\left(-4s\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

2s-4s

\mathrm{Add\:similar\:terms:}\:2s-4s=-2s

-2s

Therefore,

2s+\left(-4s\right)=-2s is the equivalent expression as 2s+\left(-4s\right) is equal to -2s.

Keywords: equivalent expression, like terms

Choose the correct correspondence RT​
Marizza181 [45]

<u></u>RT corresponds to TR. correct option b.

<u>Step-by-step explanation:</u>

In the given parallelogram or rectangle , we have a diagonal RT . We need to find which side is in correspondence with side/Diagonal RT of parallelogram URST .

<u>Side TU:</u>

In triangle UTR , we see that TR is hypotenuse and is the longest side among UR & TU . So , TR can never be equal in length to UR & TU . So there's no correspondence of Side TU with RT.

<u>Side TR:</u>

Since, direction of sides are not mentioned here , we can say that TR & RT is parallel & equal to each other . So , TR is in correspondence with side/Diagonal RT of parallelogram URST .

<u>Side UR:</u>

In triangle UTR , we see that TR is hypotenuse and is the longest side among UR & TU . So , TR can never be equal in length to UR & TU . So there's no correspondence of Side UR with RT.

17/9 15 divided 6 divided 30 divided and 3^3 from least to greatest
qaws [65]

I assume you mean: Order the following from least to greatest:

17/9, 15 divided by 6, 30, and 3^3

17/9 = 1 8/9

15/6 = 2 1/2

3^3 = 9

So it would be: 17/9, 15 divided by 6, 3^3, and 30

Make necessary adjustments if it was actually 6/30; the wording was confusing.

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level, how long will
navik [9.2K]

Answer

Find out the how long will it take the submarine to descend to the ocean floor

To proof

Formula

r = \frac{d}{t}

where  d  =  distance traveled (or descended),

r  = rate of travel , t  = time

As given

A submarine descends at a rate of 2.6 kilometers per hour. If the ocean floor is 6.24 kilometers below sea level .

put all the values in the above formula

2.6 = \frac{6.24}{t}

t = \frac{6.24}{2.6}

t = 2.4 hour

it take 2.4 hours the submarine to descend to the ocean floor .

Hence proved
