Answer:
24 and 48
Step-by-step explanation:
Let's let the two numbers be a and b.
Their sum is 72. So:
One number (let's use a) is two times another (b). In other words:
We have a system of equations. We can solve by substituting the second equation into the first. So:
Combine like terms:
Divide both sides by 3:
So, one of the numbers is 24.
Since their sum is 72, this means that the other number is 72-24 or 48.
So, our two numbers is 24 and 48.
And we're done!
I would have wished to see Venn Diagram, however I will try to answer this problem:
A={1,2,3,4}
B={1,2,5,6}
(A∩B) ={1,2}
The complement of (A∩B) is (A∩B)'
(A∩B)' = A'∪B' (De Morgan's law)
A' ={5,6} and B'={3,4}
A'∪B' = {5,6} ∪ {3,4}
A'∪B' = (A∩B)' = {3,4,5,6}
A double negative makes a positive
-9 - (-4) = -9 + 4 = -5
If the whole angle (ABC) is equal to 133, we can add angles ABD and DBC to find x.
10x+13=133
Subtract 13 from both sides to get
10x=120
Divide both sides by 10 to get that x=12
We can now plug the value of x into ABD to find its measure.
7(12)+4
Simplifies to 84+4, which is 88
So angle ABD is equal to 88 degrees.

Answer: C. N </h3>
N stands for Newtons
In terms of SI units, 1 newton = 1 kg m/s^2
It's based off the equation F = ma, which is Newton's second law.

Extra info:
- Choice A is velocity
- Choice B is acceleration
- Choice D is some unit I don't really recognize, so I'm not sure if its nonsense or it may have some use. Though I'm sure that N/s isn't a measurement of force.
