George and Carmen went on a bicycle trip. They took a bus to their starting point, and then biked the rest. They traveled 300 kilometers in total, and they biked 70 kilometers more than they were bussed.

Let x = kilometers traveled by bike and y = kilometers traveled by bus.

185 km

Step-by-step explanation:

[(300-70)/2] + 70 = 185

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
