15. 1hour 7minutes and 5seconds
30% of 47.50 is 14.25 so the amount payed the person payed in total would be 33.50
0.30 x 47.50 = 14.25
47.50 - 14.25 = 33.50
Step-by-step explanation:
2(3x + 5y = -19)
6x + 10y = -38
5 (5x -2y = 16)
25x - 10y = 80
19x = 42
but idk from there the rest doesn't work Soo if u can find the prob and tell me I'll fix it.
Let's look at it like this:
5/10+1/5 = (5/10) + (1/5)
5/10 = 0,5
1/5 = 0,2
so it's 5/10 + 1/5 = (5/10) + (1/5) = 0,5 + 0,2 = <u>0,7 </u>
