2x = -3
x = -3/2

Kilo means thousand, so if you have 1 kilogram that means you have 1000 grams.
Paulina has a 2.5 kilogram mass, 2 kilograms is 2000 grams.
0.5 means half and to get a half out of anything you have to divide it by 2.
1000 divide by 2 is 500.
Your answer is 2500.
Answer:
13 years
Step-by-step explanation:
Let the unknown number of years be n.
Then 72 + n = 5(4 + n)
Performing the indicated multiplication,
72 + n = 20 + 5n
Grouping like terms gives us:
52 = 4n, and so n = 13.
In 13 more years, Ishaan will be 5 times over than William.
