Pavel [41]

Answer:

The fourth option is the correct answer

Step-by-step explanation:

The given expression is

-2n(5+n-8-3n)

Given that n=3,We substitute the value of n into the expression and simplify.

This implies that,

-2n(5+n-8-3n)=-2(3)[5+3-8-3(3)]

=-6(5+3-8-9)

=-6(-9)

=54

Hence the answer is 54

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.
