To simplify <span>2x + 8 = -6, the easiest way is to manipulate the equation one step at a time:
</span>2x + 8 = <span>-6
</span>2x = <span>-14 (subtract 8 from both sides)
</span>x = -7 (divide both sides by 2)
If you would like to write 0.423 as a percent, you can calculate this using the following step:
0.423 * 100% = 42.3%
The correct result would be 42.3%.
b^2-4ac<0 b^2-144<0 (b-12)(b+12)<0
-12<b<12
Answer:
7.5 feet long
Step-by-step explanation:
if I had one, 5 foot sandwich, I would have 8 pounds. if I had 2.5 more foot of sandwich I would have 4 more pounds ( because 2.5 feet is half of 5 feet which means we would have to divide 8 pounds by 2). which means I have 8 pounds and 4 pounds, which equals 12 pounds. I also have 5 feet and 2.5 feet of sandwich which is equal to 7.5 feet. since it's asking the length of a 12 pound sandwich, your answer is 7.5 feet long.
Answer:
The variables change
Step-by-step explanation:
Since we can't subtract c from -b we multiply both variables by a because the question is telling us to subtract b and c then multiply the awnser by a, but we don't know what b and c is so we just multiply b and c by a. In the end we get ab-ac
