Answer: The equation that represents this situation is -3x = 21. The second number is -7 (option C).
Step-by-step explanation:
Hi, the correct option is C.
We have to analyze the information given to write the equation and corroborate the option chosen.
So:
first number = -3
Product means the result of multiplication, in this case, the product is number 21.
Mathematically speaking:
-3x= 21
x = 21/-3
x = -7
In conlclusion, he equation that represents this situation is -3x = 21. The second number is -7 (option C).
