A company that offers tubing trips down a river rents tubes for a person to use for $20 and “cooler” tubes to carry food and wat
Licemer1 [7]

<u>Answer:</u>

The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water  

<u>Explanation:</u>

The rents for tubes for a person to use = $20

The rents for “cooler” tubes to carry food and water = $12.50.

The rent for a total of 15 tubes = $270

11 tubes whose rent cost  $20 =11 \times 20

                                                   = 220

4 “cooler” tubes rent cost  $12.50 =4 \times 12.5

                                                   = 50

Therefore for 15 tubes = 11 +4= 15

                            cost = 220 + 50

                                    =270                                                  

The number of each type of tube does the group rent is 11 tubes for person and 4 “cooler” tubes to carry food and water

AB≅BC≅CD≅DE, AD = 8x - 4, AB = x + 2 solve for AB
Levart [38]

Just solve for , then substitute back into either expression and calculate either BC or AD. The other one is then the same amount.


The one about the square is the same thing except you don't care how the figure is named because all 4 sides are equal anyway. Just set the two expressions equal to one another and then solve for
