Answer:
6825
Step-by-step explanation:
From the equation, the series is a geometric series, such that
a = 5
r = 4
n = 6
sum of a geometric series is a(r^n - 1)/(r - 1)
therefore,
sum of the series is 5 x (4^6 - 1) / (4 - 1)
= 5 x (4096 - 1) / 3
= 5 x 4095 / 3
= 6825
Answer:

Answer: 24.8
Step-by-step explanation:
When it says "is a less than b" , it means b - a not a-b.
x+y +z = 105
z = 10y - 11
2x = 3y + 7
Substitute expressions in terms of "y" for x and z in top equation.
Substitute value of y to find x and z:
