Question

HELP ASAP I WILL GIVE BRAINLIEST, WORTH 20 POINTS

Answer 1

Answer:

3) 2 only.

Step-by-step explanation:

The given inequality is

$7x+8>20$

To solve this inequality, we just need to solve for $x$. First, we move the term 8,

$7x>20-8\\7x>12$

Then, we move the factor 7 to the other side of the sign,

$x>\frac{12}{7}$

This means the set of solutions for the inequalit are all the numbers that are greater than 12/7.

Therefore, the right answer is 3) 2 only. Because, the sign of the inequality indicates that solutions must be GREATER than 12/7, not equal.

Answer 2

The answer to the question is 2.)2.5 because when you substitute 12/7 into the inequality you get 20 which is not greater than 20 and when you substitute -3 you get -13 which is also not greater then 20 but when you substitute 2.5 you get 25.5 which is greater than 20
