9/2{8-x}+36=102-5/2{3x+24}
you first use 9/2 to open brackets
9/2*8=36,
9/2*x=9/2x
36-9/2x=102-5/2{3x+24}
5/2*3x=15/2x+60
36-9/2x=-15/2x-60
36+60=15/2x+9/2x
96=12x you then divide and the answer obtained will be 8.
x=8

Answer:

4^n-1

Step-by-step explanation:

So given sequence is a geometric sequence where terms increase or decrease by a constant common ratio(r)

Formula to find terms in Geometric sequence is " ar^n-1 where a is first term , r is common ratio and n is number of items

In this case , first term (a) is 1 , common ratio(r) is succeeding term/preceding term = 4/1 = 4 and number of items be (n).

Applying "ar^n-1 " we get,

1*4^n-1 which is , 4^n-1

Thats the formula which represents the situation....

The volume of  a pyramid with hight and base is 1/3 the volume of a rectangleular prisim with the same height and base

also the volume of  a cone is 1/3 the volume of a cylinder with same height and base so
just fun facts to know (helpful)


so volume of cylinder=1/3 times height tiimes pi times radius^2
subsitute
use pi=3.14
height=12
radius=6
volume=1/3 times 12 times 3.14 times 6^2
volume=4 times 3.14 times 36
volume=452.16 cubic meters
