zvonat [6]

The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches

So the answer can be solved like this:

1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)

or

1/3in to 3in which is also 9:1 (blueprint size to actual size)

Solve this inequality for x: -46 − 8x &gt; 22. A. x &lt; 8.5 B. x &lt; -8.5 C. x &gt; -8.5 D. x &gt; 8.5
marissa [1.9K]

Step one rewrite: -46-8x>22

Add 46 to both sides: -8x>68

Divide both sides by -8 to isolate x<-8.5

(remember to flip the inequality sign when multiplying or dividing by negative numbers in inequality problems)

So the correct answer is B. x < -8.5
