ITS DUE TODAY HELP PLS Which steps would be used to solve this equation? Check all that apply. Multiply by 3 on both sides of th

kumpel [21]

Answer:

Multiply by 3 on both sides of the equation.

2.78 × 3 = 8.34, so t = 8.34.

Substitute 8.34 for t to check the solution.

Step-by-step explanation:

To solve the equation = 2.78

we will use the steps below to solve this equation;

First, multiply by 3 on both-side of the equation. That is;

× 3= 2.78 × 3

On the left hand side of the equation 3 will cancel-out 3, leaving us with just t while 3 will be multiply by 2.77 on the right-hand side of the equation to give 8.34

t = 8.34

we can further substitute 8.34 for t to check the correctness of the solution

that is;

= 2.78

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

Explanation

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 find the LCM(Least Common Multiplier) of 2 and 3. So, the LCM will be 6.

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

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