On week 1, we started with a deposit of $200. Every week from that point on, we place a deposit of $55.
We know y is total amount of money (deposits) in the bank account.
We also know x represents the number of weeks.
On week 1, we would have $200 in the back account.
On week 2, we would have $200 + $55 or $255 in the bank account.
So, we could build an expression of 55(x - 1) + 200 which is equal to y.
So, y = 55(x - 1) + 200 is the answer.
Using it's formula, it is found that the area of the circle, in square units, is of .
<h3>What is the area of a circle circumscribed about an equilateral triangle?</h3>
Considering that the equilateral triangle has side length l, the area of the circle is given by:
In this problem, the sides have lengths of 9 units each, hence l = 9 and:
The area of the circle, in square units, is of .

This question was once asked before so I will put it here.
The correct answer for the question that is being presented above is this one: "x = 2; a = 5; b = 3" A 5 inch tall bamboo shoot doubles in height every 3 days. If the equation y=ab^x, where x is the number of doubling periods, represents the height of the bamboo shoot.
F = final amount = unknown
P = 7000 is the principal (amount loaned)
i = 0.05 is the decimal form of 5% interest rate
t = 3 years go by
Plug those three values into the formula below and simplify
F = P*(1+i)^t
F = 7000*(1+0.05)^3
F = 7000*(1.05)^3
F = 7000*(1.157625)
F = 8103.375
F = 8103.38
<h3>Answer: Choice A) $8,103.38</h3>
8q+4=20
8q=16
q=2
