If Anna and Tamera drive 5x - 5 hours over the four days and the plan to travel 4.5 hours each day (x = 4.5), how many hours will they drive over the four days? Note
the expression 5x - 5 represents the total time traveled.

17.5 hours

Step-by-step explanation:

5x-5 over 4 days and the plan to travel 4.5 hours each day. WE have to find how many hours will they drive each day. Now, to find the total time  pu x to 4.5 in the above expression. 5(4.5)-5

= 22 * 5-5 = 17. 5 hours over the four days of traveling

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
