11. 5x + 5 what does it equal to

Shkiper50 [21]

Answer:

Step-by-step explanation:

Okay this is an odd question, but what i'm thinking is that

first you have

5x+5

To actually be able to solve we have to move the 5 to the other side.

To do this we subtract it.

Making the equation

5x = -5

Then you need to isolate the variable (X)

So divide 5X by 5, and then divide -5/5

Which leaves you with:

x=-1

Find the infinite sum of 10,5,2.5,1.25...

____ [38]

Notice this is a geometric progression since each number multiplied by some factor equals the next number in the sequence, in this case,

$10 \times r = 5 \Rightarrow r=0.5$

Then by applying the formula for sum to infinity of a geometric progression,
$S_\infty = \frac{a}{1-r} = \frac{10}{1-0.5} = 20$
