We can solve problems like this using multiplication rules. Since the order of colors and combinations does not matter, we can multiply all values in any order we so choose. In this case, our values are colors and vehicles:
Car: Red, Yellow
Truck: Black, White, Silver
Motorcycle: Green, Blue, Orange
We have 2 options with a car, 3 options with a truck, and 3 options with a motorcycle. Since he wants one of each, we will multiply all of the color options together:
2 x 3 x 3
= 18
Edwin has 18 different combination of vehicles to choose from.
For the first Q the answer is the first square on the left 10 miles divided by 12 hours = 0,83 miles
And the second Q goes with the last square 12 hours divided by 10 miles = 1.2 h which in minutes is 72 minutes or 1h and 12 minutes.
Answer:
xy = 3
Step-by-step explanation:
The expression to be evaluated is:


By some algebraic handling:

Where:

There is one possible solution:
x = 3, y = 1
And consequently,
xy = 3
