1 trillion is 10^9.
Thus, 21 1/2 trillion is 21 1/2 times 10^9, or 2.15 times 10^10
Hope this helps. If not, ask for clarification.

Step-by-step explanation:
Let's solve your equation step-by-step.
5.1+2.3x=23.5
Step 1: Simplify both sides of the equation.
2.3x+5.1=23.5
Step 2: Subtract 5.1 from both sides.
2.3x+5.1−5.1=23.5−5.1
2.3x=18.4
Step 3: Divide both sides by 2.3.
2.3x
2.3
=
18.4
2.3
x=8
Answer:
x=8
Answer:
Step-by-step explanation:
Firstly you must understand you want to get the value of y.
So put in values into equation which make x.
To understand here lets look at y = 0
if y is to be 0 then x is 3.
If we substitute this value into equation (B) we get the result.
Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.
So , we can see B is the answer
Answer:
15600 ways
Step-by-step explanation:
In this case what we must is to calculate the number of permutations since the order does matter, we know that the alphabet has a total of 26 letters and are 3 names, the first, the middle and the last.
n = 26 and r = 3
nPc = n! / (n-r)! = 26! / (26-3)!
nPc = 15600
that is to say that there are a total of 15600 ways to form these names
