Answer:

Step-by-step explanation:
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.888.. (1) ← multiply both sides by 10
10x = 8.888.. (2)
subtract (1) from (2) thus eliminating the repeating digits
9x = 8 ( divide both sides by 9 )
x = 
Answer:
x = 4/3
Step-by-step explanation:
Step-by-step explanation:
b=1/2hr
2hr × b = 1
2hrb = 1
to find h divide both sides by 2rb
h = 1/2rb
-15x=-4x
We know that adding zero wouldn’t change the value
-15x=-4x+0
Now we can add 4x (since that’s the opposite of the negative sign) to the other side
-11x=0
0 divided by 11 is 0
x=0
