Answer:
20 1/2 feet
Step-by-step explanation:
The total length is found by adding the lengths of the individual pieces. It can be easier if you use multiplication in place of repeated addition. You want ...
(2 × 5 feet) + (7 × 18 inches)
At some point in the process, you need to convert inches to feet. This is done by remembering that 12 inches = 1 foot. Dividing inches by 12 gives feet.
The above expression evaluates to
10 feet + 126 inches = 10 feet + (126/12) feet = 10 feet + 10.5 feet
= 20.5 feet

A Google search box is a capable units converter and calculator.
First we know that:
AB+BC=AC
now , since B is the midpoint of AC, this means that AB=BC
therefore,
AB+BC=AC can also be written as
AB+AB=AC
3x-1+3x-1=8x-20
6x-2=8x-20
-2+20=8x-6x
18=2x
x=9
therefore:
AB=3(9)-1=27-1=26
AC=8(9)-20=52
BC=AB=26
