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
Answer:
2 1/3 meters
Step-by-step explanation:
You would simply divide 14 by 6 which gives you 2.3 repeating and 0.3 repeating is the fraction 1/3.

Answer:
10 packages of hot dogs bought.
Step-by-step explanation:
It is 10. It says that you bought 12 packages of MEAT, not hot dogs alone. So...
$4 * 10
= $40
$10 * 2
= $20
$40 + $20
= $60
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)
