27 blue balloons

Step-by-step explanation:

Salina was at a party and she noticed that the room had 54 balloons.

For every red balloon there were 2 yellow and 3 blue balloons.

This is written in the form of ratio as = 1 : 2 : 3

First we calculate the number of red balloon.

54 / (1 + 2 + 3)

= 54 / 6 = 9 red balloons

For every red balloons there were 3 blue balloons.

Therefore, Blue balloons = 9 × 3 = 27 blue balloons

27 blue balloons were in the room.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
