Answer:
12 over 15 and 1 over 15 i think
Step-by-step explanation:
so we have 3 folks painting 4 walls, now each one of them works for 32 minutes
person 1............. 32 mins
person 2............. 32 mins
person 3............. 32 mins
for a total of 32+32+32 = <u>96 minutes worth of work</u>. That's for 4 walls, how many minutes worth is just 1 wall?
96 ÷ 4 = 24 mins.
so to paint a wall, it takes 24 mins of work worth.
so then, to paint 7 walls, that'd be 7 * 24 = 168 minutes worth of work.
what about for 4 folks doing it? How many times does 4 go into 168? 168 ÷ 4 = 42 mins.
15:24 to the lowest term is 5:8. This is because you divide each number by the same number. You will divided 15 and 24 by 3 to get 5:8.
so what i did was a long process but it worked i started by taking $5550 and multiplying it by .12 which gave me $666 then i did 9500-5550=3950 then i took 3950 and multiplied it by .09 and it gave me 355.5 then i added those together and got 1021.5 so i needed to increase the amount i invested at 12% to get a higher yield. i did this process a few more times and each time i increase the amount of money i invested at 12% by 25 dollars and i finally arrived at:
5900 x .12 = $708
9500-5900=3600
3600 x .09 =$324
708+324= $1032
so your answer is that you invested $5900 at 12% and $3600 at 9%.
add me as a friend if you like because i am generally good at math. hope this helped.
Answer:
x-12=66 or 78 -12 =68
Step-by-step explanation:
3+2= 5 ||| 5 is the answer, sum
difference 12 || difference= subtract
