So, I'm not use to that type of currency, but I can still help you. The equation would be: 145 + 60(d-1) = 445 Now since it is 60 per day after that, the first day would not be charge, the second would but you would not charge it more. 145 + 60d - 60 = 445 Add like terms 85 + 60d = 445 -85 -85 60d= 360 d= 6 You can even check using a table/ coordinates. x= days, y=money (1, 145), (2, 205), (3, 265), (4, 325), (5, 385), (6, 445).
First we need to find the base, which is 6 and the height which is 7. Then, multiply 6 and 7 to get 42. Then add your units, which are meters. So, 42m is your answer. I hope this helps! :)
Since the ratio is part-Whole, first you need to find the whole. If you add all of the marble colors together (17+13+23) you get the total marbles (53) in the box. The ratio of red marbles to the total would be 17 to 53.
