-3+11x
1) montly rate, r = 5% / 12 = 0.416% = 0.00416
2) capital, C = $ 450 = present value
3) time = 11 years => number of periods = 11 * 12 = 132
4) Formula: FV = C * (1 + r) ^ (number of periods)
5) Calculation: FV = $450 * ( 1 + 0.00416)^(132) = $ 779.07
Answer: $ 779.07

In the attachment, the quotient is calculated "by hand" to 7 decimal places (6 significant figures). The quotient is a repeating decimal with a 180-digit repeat.
This is a good problem for your calculator.
Answer:
x = 2.25, y = 2.5
Step-by-step explanation:
-2x + 2y = -2 .............equ (1)
2x + 3y = 12 .............equ (2)
equ (1) + equ (2)
-2x + 2y = -2
+ 2x + 2y = 12
=> 0 + 4y = 10
=> 4y/4 = 10/4
=> y = 2½
Substitute for y in equ (2)
i. e, 2x + 3y = 12
=> 2x + 3(10/4) =12
=> 2x + 30/4 = 12
=> 2x = 12 - 30/4
=> 2x = (48 - 30)/4
=> 2x = 18/4
=> 8x = 18
=> x = 18/8
=> x = 2^2/8 or 2.25
x = 2.25, y = 2.5
William has $240 to Michael's $420
this can be written in a ratio as 240 : 420
which can then be reduced to
24:42
12:21
4:7
