Aparty rental company has chairs and tables for rent. the total cost to rent 5 chairs and 2 tables is $23 . the total cost to rent 3 chairs and 8 tables is $58. what is the cost to rent each chair and each table?
-cost to rent each chair: $
-cost to rent each table: $

Step-by-step explanation:

The two different rentals give rise to two equations. Let t and c represent the rental costs of a table and chair, respectively. The rentals are ...

  5c +2t = 23

  3c +8t = 58

Cramer's rule tells you ...

  c = (2·58 -8·23)/(2·3-8·5) = -68/-34 = 2.00

  t = (23·3 -58·5)/-34 = -221/-34 = 6.50

The cost to rent each chair is $2.00.

The cost to rent each table is $6.50.

Cramer's Rule says the solution to

  ax +by = c

  dx +ey = g

is ...

  x = (bg -ec)/(bd -ea)

  y = (cd -ga)/(bd -ea)

When the equation's coefficients are not convenient to achieve elimination of a variable, Cramer's rule can get to the solution very quickly. The same number of math operations are involved, but they are expressed in terms of a formula that can be used with no guesswork.

if this is really you s much. i only have 3 points left and i have 2 questions to ask

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
