Aschool band has a brass section of trumpet, trombone, and tuba players. there are twice as many trombones as tubas, and half as many trombones as trumpets. if there are two tubas in the band, what is the total number of players in the brass section?

There is 14 players in brass section.

Step-by-step explanation:

Given : A school band has a brass section of trumpet, trombone, and tuba players. There are twice as many trombones as tubas, and half as many trombones as trumpets. If there are two tubas in the band.

To find : What is the total number of players in the brass section?

Solution :

Let x be the number of trumpets.

Let y be the number of trombones.

Let z be the number of tubas.

→ There are twice as many trombones as tubas.

 ........[1]

→ Half as many trombones as trumpets.

 .........[2]

→ There are two tubas in the band.

 ..........[3]

Now, we solve these three equations,

Put z=2 from [3] in [1]

Now, put the value of y in equation [2]

Total numbers of players in brass section is

Therefore,There is 14 players in brass section.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
