So,

Multiply both sides by 11.

Divide both sides by 7.
f = 1
Check.


This checks.
S = {1}
((4x+15)/(5x)) = 1/2
4x+15 = (5x)/2
8x+30=5x
3x+30=0
3x=-30
x=-10
For num 4 the answer to six is 22 the reason is this formula so write this down for n aswell
n(n+1)/2+1 the example could be as we know for 1 cut we always will have 2 slices so 1(1+1)/2+1 is 2 and for 6 cuts 6(6+1)/2+1 is 22 therefore the answer to 6 cuts is 22 and to n cuts is the formula n(n+1)/2+1
Answer:
The correct answer is <em><u>11/2.</u></em>
Answer:
no it is really easy question to answered so do it your self
