-9 for the w ...........
nasty-shy [4]3 years ago
7 0

Answer:

Just divide -8 on both sides because you want to isolate the variable. Remember, whatever you do to one side, you must do to the other. So 72/-8 is -9. That means...

w= -9

Also remember, two negative numbers multiplied make a positive, and one negative and one positive number makes a negative number.

The ratio of violinists to cellists in the school orchestra must always be 7:3. If the school orchestra has 21 violinists, what
Papessa [141]

Given:

Violinists : Cellists = 7:3.

Number of violinists in the school orchestra = 21

To find:

The combined number of cellists and violinists.

Solution:

Let the number of violinists and cellists in the school orchestra are 7x and 3x respectively.

Then, combined number of cellists and violinists is

\text{Combined number of cellists and violinists}=7x+3x

\text{Combined number of cellists and violinists}=10x      ...(i)

Number of violinists in the school orchestra = 21

7x=21

Divide both sides by 7.

x=3

Now, the combined number of cellists and violinists is

\text{Combined number of cellists and violinists}=10(3)    [Using (i)]

\text{Combined number of cellists and violinists}=30

Therefore, the combined number of cellists and violinists is 30.
