Robbie is preparing for a marathon. altogether, robbie ran a total of 43 miles. how many miles did
robbie run on friday? here is his training schedule:
• monday: ran x miles.
• tuesday: ran double the miles he ran on monday.
• thursday: ran half the miles he ran on monday,
• friday: ran triple the miles he ran on monday morning plus 4 more miles in the evening.

show the equation to solve for it, the answer, and the steps of solving the equation. you~

13 miles

Step-by-step explanation:

43-4=39      you use the inverse operation. you subtract 4 from 4, you get 39.

39/3=13       then, you also do the inverse operation. you divide 39 by 3, you        

                   get 13 as your answer.

i have no idea just need points sorry

step-by-step explanation:

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.
