Fifteen years later, a man will be two times as old as he was 15 years ago. How old is he now?
Inga [223]

Answer:

Let the present age of the man be x years.

Age of the man 15 years ago =(x−15) years and

Age of the man 15 years later =(x+15) years

According to the given condition, we have

(x+15)=2(x−15)

⇒x+15=2x−30

⇒x−2x=−30−15

⇒−x=−45 or x=45 years

Hence, the present age of the man is 45 years.

Step-by-step explanation:

Hope it helps you..

Your welcome in advance..

Which is bigger 0.17 or 0.165 meters
zavuch27 [327]
Your numbers are .17 and .165 meters

Let me explain each digit value:

Lets start with .17

Decimals are like whole numbers where each placement has a digit value

.1 is the tenths place

.07 is the hundredths place

Lets turn to .165

.1 is the tenths place

.06 is the hundredths place

.005 is the thousandths place

When seeing which decimal is larger, go along the tenths place and move along.


So as you can see
, .17 and .165 start with .1 so you can't see which is bigger by this. Now move on to the next digit. Which is larger? .17 or .16? As you should know, 7 is bigger than 6 so that means .17 is larger

Answer: .17 meters is larger than .165 meters

you'll end up with 4x + 4 = 7672
thus x = 1918 and the next number is 1920.
