Answer:

a) x=5

b) x=6

Step-by-step explanation:

3x+7=180-(10x-22)

3x+7=202-10x

13x=195

x=5

11x-3=4x+39

7x=42

x=6

I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.

Fine the sum of the series

lapo4ka [179]

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
