I need to know the answer please…
Triss [41]
Answer is a= 51/7 or 7 2/7

Step by step

-2/3 (a + 3) = 5/3a - 19

Distribute to resolve parentheses

-2/3a -2 = 5/3a - 19

Now to move variables to one side
Add 2/3a to both sides

-2/3a + 2/3a -2 = 5/3a + 2/3a -19

Combine like terms

-2 = 7/3a -19

Add 19 to both sides to isolate variable

-2 +19 = 7/3a -19 + 19

17 = 7/3a

Divide both sides by 7/3 to solve for a
(Remember when you divide a fraction, flip it and multiply.)

17 * 3/7 = a

51/7 = a

Picture attached shows steps in order, I think that is what you also needed?

A radio station plays yesterday by the beatles once every 2 days. Another station plays the same song once every 3 days. How man
mel-nik [20]

Both radio stations will play the same song on the same day <u>5 times</u> in 30 days.

<u><em>Explanation</em></u>

A radio station plays yesterday by the Beatles once every 2 days. Another station plays the same song once every 3 days.

For finding the day on which both radio stations will play the same song, we will just <u>find the LCM(Least Common Multiplier) of 2 and 3</u>. So, the LCM will be 6.

That means, <u>on every 6th day, both radio stations will play the same song</u>.

So, the number of times that both radio stations will play the same song on the same day in 30 days =(\frac{30}{6})= 5
