Answer:
The first step would be to multiply 2x - 1 by 6, which would be 12x - 6 .
Answer:
180-44=136 is d
then 180-136=44 44/2=22
c is 22. just remember total angle above straight line is 180, and the total angle of a triangle is also 180. And if two sides have the same length, their angles are also the same like c and a, and e and 44 degrees
Answer:
98-54+12-36
110-54-36
56-36
20<em>A</em><em>n</em><em>s</em>
I would think A because regular quadrilaterals have 90-degree angles.

I want to find the amount of antifreeze in a 15 quart solution with 30% antifreeze
<span><span>V<span>Antifreeze</span></span>=15∗0.30</span> =18/4 quarts of antifreeze
Similarly, I want to find the amount of antifreeze in a 15 quart solution with 35% antifreeze first.
<span><span>V<span>Antifreeze</span></span>=15∗0.35</span> = 21/4 quarts of antifreeze
<span>the difference between 21/4 and 18/4 is 3/4 quarts, which is the amount of pure antifreeze I've added in.

SO the V_fluid I replaced with 3/4 quarts of antifreeze is (3/4)/ 0.35</span>
