\overline{LK}\cong\overline{MK}\\LK=MK=7x-10\\KN=x+3\\MN=9x-11\\KJ=28\\\\MN=MK+KN\\\text{therefore we have the equation:}\\9x-11=(7x-10)+(x+3)\\9x-11=8x-7\ \ \ |+11\\9x=8x+4\ \ \ \ |-8x\\x=4

LJ=LK+KJ\\\\LK=7x-10\to LK=7(4)-10=28-10=18\\\\\text{therefore}\\LJ=18+28=46

Answer: LJ = 46.

The table shows the number of cell phone towers a
Olin [163]

Answer:

The correct option is;

B. Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of 52 Towers/(Thousand customers)

Step-by-step explanation:

The given data can be presented as follows;

Cell Phone Towers

Customer (thousands)    {}   Towers

1) 5.25            {}                          273

2) 6.25            {}                         325

3) 7.25            {}                         377

4) 9.25            {}                         481

From the given data, we have the ratio Towers/Customer (thousands) given as follows;

For 1), we have;

273 Towers/(5.25 thousands customers) = 52 Towers/(Thousand customer)

For 2), we have;

325 Towers/(6.25 thousands customers) = 52 Towers/(Thousand customer)

For 3), we have;

377 Towers/(7.25 thousands customers) = 52 Towers/(Thousand customer)

For 4), we have;

481 Towers/(9.25 thousands customers) = 52 Towers/(Thousand customer)

Therefore, the ratios of towers to customers (thousands) all have the same equivalent unit rate of 52 Towers/(thousand customers).
