Answer:

Step-by-step explanation:

The sequence of payment is geometric , that is

1, 3, 9, ...

The sum to n terms of a geometric sequence is

$S_{n}$ = $\frac{a(r^{n}-1) }{r-1}$

where a is the first term and r the common ratio

Here a = 1 and r = 3 ÷ 1 = 3 , then

$S_{15}$ = $\frac{1(3^{15}-1) }{3-1}$ = $\frac{14348907-1}{2}$ = $\frac{14348906}{2}$ = 7174453 cents and

7174453 ÷ 100 = $71,744.53 → A

7x - 2 = 2y 3x = 2y - 1

77julia77 [94]

7x - 2 = 2y
7x = 2y + 2
so
7x = 2y + 2
3x = 2y - 1
----------------subtract
4x = 3
x = 3/4

7x - 2 = 2y
7(3/4) - 2 = 2y
21/4 - 2 = 2y
21/4 - 8/4 = 2y
13/4 = 2y
so
y = 13/4 * 1/2
y = 13/8

answer
(3/4, 13/8)

VikaD [51]

Answer:

x=2, y=3. (2, 3).

Step-by-step explanation:

2x+4y=16

-2x-3y=-13

-----------------

y=3

2x+4(3)=16

2x+12=16

2x=16-12

2x=4

x=4/2

x=2
