Please answer quickly, it’s inequalities and it’s very confusing.

A

Step-by-step explanation:

It is A, because it tells you the equation of

-5x + 8 ≥ -7

Because the key on the right tells you that shaded squares are negative and white ones are positive.

You can then subtract both sides by 8 to isolate the -5x and the equation becomes:

-5x ≥ -7 - 8

Which simplifies to

-5x ≥ -15

which you can now divide both sides by -5 to get

x ≥ 3

BUT WAIT

the general rule is that when you divide a variable (in this case x) by a negative number, you have to flip the inequality sign

so ≥

should become ≤

so the equation is x ≤ 3

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
