The formula of the length of the segment AB:

We have:

Substitute:

Answer:
B) 10.
Answer:
x=13
Step-by-step explanation:
(4x-20+x-1)/8 = (3x-9+4x-16)/12
(5x-21)/8=(7x-25)/12
(5x-21)/8 x 12/1 = (5x-21)/2 x 3/1 = (15x -63)/2
15x - 63 = 14x - 50
x=13
Answer:
b
Step-by-step explanation:
Answer:
2/11
Step-by-step explanation:
To turn a repeating decimal to a fraction:
1) Multiply by the number of digits repeating to the power of 10. In this case, there are two digits repeating.
x=0.1818...
100x=18.1818...
2) subtract x
99x=18
3) divide by 99
x=18/99
4) simplify
x=2/11
