Answer:

y = 29/4

Step-by-step explanation:

It is given that,

3/(y - 5) = 15/(y + 4)

<u>To find the value of y</u>

we have,

3/(y - 5) = 15/(y + 4)

3(y + 4) = 15(y - 5)

(y + 4) = 5(y - 5)     [dividing both sides by 3]

y + 4 = 5y - 25

5y - 25 = y + 4

5y - y = 4 + 25

4y = 29

y = 29/4

Therefore the value of y = 29/4

wlad13 [49]

Hey there! I'm happy to help!

A proportional equation follows the form y=kx, where k is the constant of proportionality.

Answer 1 is wrong because there is something added.

2 is correct as it follows this format.

3 is incorrect as it does not follow this format.

4 is correct as it follows the format (k is 1)

5 Is correct because it follows this format.

6 is not correct because there is a 1 added, which does not follow the format.

Therefore, the correct answers are 2, 4, and 5.

Have a wonderful day! :D

Jessica, Chau, and Kareem sent a total of 84 text messages during the weekend. Kareem sent 4 times as many messages as Chau. Jes
swat32

Answer:

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9

Step-by-step explanation:

Let number of messages sent by Chau = c

Number of messages sent by Kareem = 4 times as Chau

                                                                = 4 * c = 4c

Number of messages sent by Jessica = 6 fewer messages than Chau

                                                               = c - 6

Total messages = 84

<u>c + 4c + c</u> - 6 = 84                {Combine like terms}

<u>6c</u> - 6 = 84         {Add 6 to both sides}

6c  = 84 + 6

6c = 90   {Divide both sides by 6}

c = 90/6

c = 15

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9

P = -2p - 15<br><br> I need help plz. Thanks!
mihalych1998 [28]

Answer: p=−5

Step-by-step explanation:

Step 1: Add 2p to both sides.

p+2p=−2p−15+2p

3p=−15

Step 2: Divide both sides by 3.

3p/3 = −15/3

p=−5
