The drama club is printing t-shirts for its members. The printing company charges a certain amount for each shirt plus a setup f
Setler [38]

Answer: $7.

Step-by-step explanation:

It is given that the printing company charges a certain amount for each shirt plus a setup fee of $40.

Let x be the cost of each t-shirt.

There are 21 students in the drama club. So, total cost of 21 t-shirts is

\text{Total cos}=40+21x

It is given that the t-shirt order costs a total of $187.

40+21x=187

21x=187-40

21x=147

Divide both sides by 21.

x=\dfrac{147}{21}

x=7

Therefore, the cost of each t-shirt is $7.

Find the length of side x in simplest radical form with a rational denominator
Angelina_Jolie [31]

Answer:

The length of x=3/1

Step-by-step explanation:

Given the right triangle

Ф = 30

We know that

sin Ф = opposite/hypotenuse

The opposite of angle 30° = x

The hypotenuse is = 6

so

sin 30 = opposite/hypotenuse

    1/2      = x/6           ∵ sin 30 = 1/2

     1/2 × 6 = x

     6/2 = x

       3/1 = x

Therefore, the length of x=3/1
