There his should help see below
I got 47 because...
Tn = Tn-1 + 3×2^(n -1)
Using the above formula,
T2 = 2 + 3×2^(1-1) = 2 + 3×2^0 = 2 + 3 = 5
T3 = 5+ 3×2^(2-1) = 5 + 6 = 11
T4 = 11 + 3×2^(3-1) = 11 + 12 = 23
T5 = 23 + 3×2^(4-1) = 23 + 24 = 47
X is shirt type 1, y is shirt type 2
x+y=5
<span>
5x+10y=35
</span>Use elimination.
solve for y
plug in y in one of the equations to find x
Answer: Hi I think that I can help you with your problem!
Let which means
Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.
To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.
So, we can rewrite as:
......(1)
Now, let us multiply the above with 10.
....... (2)
Now, let us subtract (1) from (2):
So, in simplified fractions:
