Answer:
There are 20 booths and (38 - 20), or 18, tables
Step-by-step explanation:
Represent the number of tables with t and the number of booths with b.
We need to find the values of t and b.
(6 people/table)(t) + (4 people/booth)b = 188 (units are "people")
t + b = 38 (units are "seating units")
Solving the second equation for t, we get 38 - b = t.
Substitute 38 - b for t in the first equation:
(6 people/table)(38 - b) + (4 people/booth)b = 188
Then solve for b: 6(38) - 6b + 4b = 188, or:
228 - 2b = 188, or 2b = 228 - 188, or 2b = 40. Thus, b = 20 (booths)
There are 20 booths and (38 - 20), or 18, tables.

∴ The true statement is Answer:
The true statement is BD ≅ CE ⇒ 3rd answer
Step-by-step explanation:
- There is a line contained points B , C , D , E
- All points are equal distance from each other
- That means the distance of BC equal the distance of CD and equal
the distance of DE
∴ BC = CD = DE
- That means the line id divided into 3 equal parts, each part is one
third the line
∴ BC = 1/3 BE
∴ CD = 1/3 BE
∴ DE = 1/3 BE
∵ BC = CD
∴ C is the mid-point of BD
∴ BC = 1/2 BD
∵ CD = DE
∴ D is the mid-point of DE
∴ CD = 1/2 CE
- Lets check the answers
* BD = one half BC is not true because BC = one half BD
* BC = one half BE is not true because BC = one third BE
* BD ≅ CE is true because
BD = BC + CD
CE = CD + DE
BC ≅ DE and CD is common
then BD ≅ CE
* BC ≅ BD is not true because BC is one half BD
∴ The true statement is BD ≅ CE
