Allushta [10]

Answer:

5 shirts must be sold.

Step-by-step explanation:

First, set up the equation. Each shirt (x) is sold for $16:

For every amount (y) for x: (y)(x) = (16)(y)

The cost is $4, with the setup fee as $60.

(16)(y) = (4)(y) + 60

16y = 4y + 60

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. First, subtract 4y from both sides.

16y (-4y) = 4y (-4y) + 60

16y - 4y = 60

12y = 60

Next, isolate the variable (y). Divide 12 from both sides.

(12y)/12 = (60)/12

y = 60/12

y = 5

5 shirts must be sold.

To check, plug in 5 for y in the equation:

16y = 4y + 60

16(5) = 4(5) + 60

Simplify.

16(5) = 4(5) + 60

80 = 4(5) + 60

80 = 20 + 60

80 = 80 (True).

MAVERICK [17]

Answer:

w = 9.82

x = 66.73

Step-by-step explanation:

By applying tangent rule in triangle ABD,

tan(81°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

6.31 = \frac{62}{w}

w = \frac{62}{6.31}

w = 9.82

Similarly,

tan(39°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

0.81 = \frac{62}{(x+w)}

0.81 = \frac{62}{9.83+x}

9.82 + x = \frac{62}{0.81}

x = 76.56 - 9.82

x = 66.74
