The operator $\geq$ is transitive, which means exactly that

$x \geq y,\quad y\geq z \implies x \geq z$

That's the only thing you can deduce from your statement.

Answer:

C. 15

Step-by-step explanation:

-4/3x-6=-26

The first step is to add 6 to each side

-4/3x-6+6=-26+6

-4/3x =-20

Now multiply by -3/4 to isolate x.

-3/4 * -4/3x = -3/4 * -20

x = 60/4

x = 15

How many terms are there in a geometric series if the first term is 3, the common ratio is 4 and the sum of the series is 1,023

Olenka [21]

The sum of a geometric sequence is:

s(n)=a(1-r^n)/(1-r) in our case:

s(n)=3(1-4^n)/(1-4)

s(n)=-(1-4^n)

s(n)=(4^n)-1 and s=1023

(4^n)-1=1023

4^n=1024

n ln4=ln1024

n=(ln1024)/(ln4)

n=5
