The answer is #1, #2, and #4

It’s #1 because if you look at a number line -3 is before -4

It’s #2 because it’s less then or equal to and -4 is equal to -4

And lastly it’s #4 because 3 is greater then -4

Hope this helps!!

The inequality 9/5C + 32 <-40 can be used to find Celsius temperatures that are less than -40 Fahrenheit. What is the solutio

Blababa [14]

The solution of inequality is C < -40

Solution:

Given that the inequality that is used to find the celsius temperature that are less than -40 fahrenheit

To find: solution of inequality

Given inequality is:

$\frac{9}{5}C + 32 < -40$

So we have to solve the above inequality for C

$\rightarrow \frac{9}{5}C + 32 < -40$

Add -32 on both sides

$\rightarrow \frac{9}{5}C + 32 -32 < -40 - 32\\\\\rightarrow \frac{9}{5}C < -72$

Multiply both the sides by $\frac{5}{9}$

$\rightarrow\frac{9}{5}C \times \frac{5}{9} < -72 \times \frac{5}{9}\\\\\rightarrow C < -8 \times 5\\\\\rightarrow C < -40$

Thus the solution of inequality is C < -40
