Question

1. \the product of a number and -4 is 80.\

Explanation:

Step1: Define the variable

Let the number be \( x \).

Step2: Translate the sentence into an equation

The product of \( x \) and -4 is \( -4x \), and this equals 80. So the equation is \( -4x = 80 \).

Step3: Solve for \( x \)

Divide both sides of the equation by -4: \( x=\frac{80}{-4}=-20 \).

Answer:

The number is \(-20\)
