Answer:
6d
Step-by-step explanation
First, you need to multiply 2d by 3, which you'll get 3d.
Next, multiply both numbers (2d and 3d) and you'll have 6d because 2 times 3 equals 6 but, since you have valuables you'd have to put d as the valuables of both numbers then multiply the numbers.
Answer:
554,700
Step-by-step explanation:
Answer:
49 litres of petrol are needed to travel from town X to town Y and back.
Step-by-step explanation:
Well, first off, the variable X and Y, as well as the distance given (124 km) aren't important pieces of information in this equation. They're only there to throw you off and confuse you.
25L of <em>p</em> (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less <em>p</em> than before it was tuned.
2%/100 = 0.02
0.02 * 25L = 0.5L
25L - 0.5L = 24.5L
Now, don't forget, at the end of the word problem we're asked how many litres of <em>p</em> would be required to travel from <em>x</em> to <em>y</em> <em><u>AND BACK</u></em>. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)
Good luck!!
