Answer:
4:6 or 2:3
Step-by-step explanation:
Since the ratio of mass of oxygen to carbon is 4:3, when there are two carbons the ratio will be 4:3*2=4:6=2:3. Hope this helps!
Step-by-step explanation:
You should prolly subtract 2 from both sides first.
So you get, -|2/5x + 3| > -1 2/5
- Add three to both sides
- -|2/5x| = -1 2/5
- Do -1 and 2/5 divided by 2/5 to get -3.5, x > -3.5
One of the answers is x > -3.5 but you need to switch the sign to less than and make the other side the opposite.

You see that, switched the sign and made whats on the right side opposite. So now solve for x again but with this new equation. Also, the parentheses are absolute value signs
Subtract 3 from both sides
-|2/5x| < -1 and 3/5
Divide 2/5 from each side to get x < -4
I hope I'm correct, my bad if I'm wrong
Answer:
1 = 128 degrees
2 = 52 degrees
3 = 47 degrees
4 = 133 degrees
5 = 81 degrees
Step-by-step explanation:
angle 2 and 52 degrees are corresponding angles so they are equal.
angle 3 and 47 degrees are corresponding angles so they are equal.
angles 1 and 2 are supplementary angles so their sum is 180 degrees.
angles 3 and 4 are supplementary angles so their sum is 180 degrees.
angle 5 = 180 - 52 - 47 = 81 degrees
