Answer:
19v
Step-by-step explanation:
3v, 7v, and 9v all have the same variable, therefor, you can add all of them up as you would regular numbers, you just have to add "v" at the end.
One example, take the conversion fact that there are 5 miles for every 8 km.
Now if we want to work out how many kilometres in 6 miles, the conversion above is not going to help straight away.
We first need to find how many kilometres in ONE mile [which is the unit rate]
5 miles = 8 kilometres
1 mile = 8/5 kilometres
1 mile = 1.6 kilometres
Once we know the unit rate, we can then work out the number of kilometres for any number of miles.
For example:
6 miles = 6×1.6 = 9.6 kilometres
25.5 miles = 25.5 × 1.6 = 40.8 kilometres
Answer:

Step-by-step explanation:
From the diagram:

Now Angle 1 and Angle 2 are on a straight line, therefore:

Answer:
c
Step-by-step explanation:
its easier to take a group of 100 or something random people than a whole population.
F(x) is most likely the f(f(x)x) where f(x) is g(x))f)) and composition can be 69 + 46 which is the total of 137
