Two consecutive even numbers are such that five times the smaller number , subtracted from eight times the bigger gives 58. Find

olga55 [171]

Answer:

$14\text{ and }16$

Step-by-step explanation:

Let the smaller number be $x$ . Since they are consecutive even numbers, the larger number can be represented by $x+2$ .

Therefore, we have the following equation:

$8(x+2)-5x=58,\\8x+16-5x=58,\\3x=42,\\x=\boxed{14}$

Thus, the larger number is $x+2=\boxed{16}$

The distance between town X and town Y is 124 kilometres and a car uses 25 litres of petrol to make the journey. after the engin

Jlenok [28]

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 p (petrol) to make the entire journey. After the engine has been tuned, it requires 2% less p 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 p would be required to travel from x to y AND BACK. So it's not only 24.5L, it's double that (24.5 * 2 = 49L)

Good luck!!
