Question

Could someone please help!!

If possible could you please give step by step on how you solve it, I have a test on these types of questions tomorrow.

Answer 1

2x > 7

Explanation:

im not completely sure this is right, but im giving this my best shot.

since the number line shows that x is greater than 3.5 (x > 3.5), and it is asking for the 2x value of that, I simply just doubled the first value (3.5).

to check, just plug any number greater than 3.5 as x.

(ex.: 2(5) > 7)

(which will be 10>7 so the statement is true)

I think you can simply plug in an x value from the number line that is true, just like 5 in that occasion, since x > 3.5, and 5 is indeed greater than 3.5 (5>3.5)

Answer 2

2x > 7

Explanation:

The open circle is at approximately x = 3.5, so the inequality represented by the line from there to the right is ...

x > 3.5

The inequality you are given to complete has 2x, so you would need to multiply both sides of this by 2:

2x > 7
