Answer:
x ≈ 61.8
Step-by-step explanation:
Using the sine ratio in the right triangle
sin15° =
=
( multiply both sides by x )
x × sin15° = 16 ( divide both sides by sin15° )
x =
≈ 61.8 ( to the nearest tenth )
Since we neither want most expensive nor least expensive, we need to go with pillow which is costing $18.49.
So total 4 pillows cost = 4*18.49
= $73.96
Given:

First, let's move the -1 to the right side. When we add
, we get
.

Now we can cross multiply, multiply (3n)(8) and (7)(9)

Simplify the left side.

Simplify the right side.

Divide both sides by 24 to isolate n.

Simplify.
