Answer:
58593
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a is the first term and r the common ratio
r = 15 ÷ 3 = 75 ÷ 15 = 5 and a = 3, hence
= 
= 
= 
= 58593
Answer:
<h2>IT'S 22 JUsT FOUND OUT </h2>
Step-by-step explanation:
anything below a growth rate of 1.025
7x - 3y = 4 => 7x = 3y + 4 => x = (3y + 4) / 7 2x - 4y = 1 => 2x = 4y + 1 => x = (4y + 1) / 2
=> (3y + 4) / 7 = (4y + 1) / 2 (3y + 4) * 2 = (4y +1) * 7 6y + 8 = 28y + 7 22y = 1 Y = 1/22 =>you can substitute y for the system of equations and find x
