Question 1What is the first step of solving cos(42)=18x? (1 point)Responsesdivide both sides by 18divide both sides by 18multiply both sides by xmultiply both sides by xdivide both sides by xdivide both sides by xmultiply both sides by 18


What is the second step?(1 point)
Responses

divide both sides by the cos(42)
divide both sides by the cos(42)

multiply both sides by cos(42)
multiply both sides by cos(42)

divide both sides by x
divide both sides by x

divide both sides by 42
divide both sides by 42

x is by itself, so you put the other side of the equation in your calculator

Answer 1

To solve the equation \( \cos(42) = 18x \), here is the step-by-step solution:

### First Step:
To isolate \( x \), the first step is to divide both sides by \( 18 \).

**Response:** divide both sides by 18

---

### Second Step:
After dividing both sides by \( 18 \), you will have:
\[ \frac{\cos(42)}{18} = x \]
To express \( x \) clearly, you can multiply both sides of the equation by \( \frac{1}{\cos(42)} \) (though not necessary since you already isolated \( x \)). However, more commonly, in practical scenarios, you would simply calculate:

**Response:** x is by itself, so you put the other side of the equation in your calculator.

You could also say the second step is conceptually understood as needing to calculate \( x \) after isolating it, which involves numeric computation with your calculator.

So for clarity:
- **First Step:** divide both sides by 18
- **Second Step:** x is by itself, so you put the other side of the equation in your calculator.
