When you go from one side to the other side of the figure you are either multiplying or dividing by 4 :)
So we’re looking how many combinations we can make by selecting 5 items in a group of 17.
So we use n C r.
Where I the number of combinations of n objects taken r at a time.
So, 17 C 5
17! / (17-5)! 5! = 6188
(I hope this is correct)
Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.
Step 2: Multiply both top and bottom by that number.
Answer:
the thalia age be 19 years
Step-by-step explanation:
Let us assume her brother age be x
Now the thalia age be x - 3
Now the equation would be
x + x - 3 = 41
2x = 41 + 3
2x = 44
x = 22
thalia age be
= 22 - 3
= 19
Hence, the thalia age be 19 years
And, her brother age be 22 years
The same is to be considered

Answer: D) $16.77</h3>
=====================================================
Explanation:
The meter goes from 9854 to 0023. You can think of 0023 as 10023 (even though the meter only has 4 digits, so it rolls over to start over again).
So,
10023 - 9854 = 169
This means 169 kw hours of electricity are used for the month of December.
The first 100 kw hours costs $4.35
There are 169-100 = 69 kw hours left, and they cost $0.18 each, so we add on 69*0.18 = 12.42 getting 4.35 + 12.42 = 16.77
