Need help with 5 and 6 and 7 please thank you
1 answer:
5) The less than symbol, using x, is <em>x < __</em>. The blank should have the number that comes after, which is <em>-15°F</em>. 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 <em>x ≤ __</em>. The number that goes into the blank is <em>127 pounds</em>, 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.
