defon

Answer:

C

Step-by-step explanation:

The first term = 1500

2nd term = 900

3rd term = 540

The series is a GP.

r = 900/1500 = 0.6

The sum of the first 10 term, S₁₀, is as calculated below.

Sn = a(1-rⁿ)/(1-r)

S₁₀ = 1500(1 - 0.6¹⁰)/(1 - 0.6)

      = 1500 × 0.9939/0.4

       = 3,727.125 m

X+2=2y then x = 2y - 2
3x-3 = 5y +1 
substitute x = 2y - 2 into 3x-3 = 5y +1 

3x-3 = 5y +1 
3(2y - 2) -3 = 5y +1 
6y - 6 - 3 = 5y + 1
y = 10

x = 2y - 2
x = 2(10) - 2 = 18

x = 18 y = 10

answer C. x = 18 y = 10 (Third choice)
