Question

1. translate the phrase below. \four less than the product of a number and 7 is eight more than that number.\ circle answer: a. 4 - 7n=n + 8 b. 4(7n)=8 + n c. 4 + 7n=n + 8 d. 7n - 4=8 + n 13. translate the phrase below. \a number less than -9\ circle answer: a. n > -9 b. n ≥ -9 c. n < -9 d. n ≤ -9 14. translate the phrase below. \a number is at least 42\ circle answer: a. n > 42 b. n ≥ 42 c. d.

Explanation:

Step1: Analyze question 12

The product of a number $n$ and 7 is $7n$. Four less than this product is $7n - 4$, and eight more than the number $n$ is $n + 8$. So the equation is $7n-4=n + 8$.

Step2: Analyze question 13

"A number less than - 9" is represented as $n<-9$.

Step3: Analyze question 14

"A number is at least 42" means the number $n$ is greater than or equal to 42, written as $n\geq42$.

Answer:

1. D. $7n - 4=n + 8$
2. (No complete option shown in the provided image, but should be $n < - 9$)
3. B. $n\geq42$
