5) The less than symbol, using x, is x < __. The blank should have the number that comes after, which is -15°F. So, that will look like x < -15°F
6) When something is at most __, that means that __ is the greatest number, which means the inequality looks like x ≤ __. The number that goes into the blank is 127 pounds, which makes the whole inequality x ≤ 127 pounds.
7) An inequality is solved similarly to an equation, with a few exceptions.
x - 3 < -15
Subtract: x < -12
That looks like what is shown in the image. The circle is empty because the inequality does not say that it contains -12, so it is skipped. It goes to the left because the inequality shows all numbers less than -12.
