Answer:
Arjun is 20 years old and Shreya is 10 years old.
Step-by-step explanation:
5 YEARS AGO-
Arjun: 2x-5
Shreya: x-5
NOW-
Arjun: 2x
Shreya: x
EQUATION-
2x-5=3(x-5) = 2x-5=3x-15
(add 15 on both sides)
2x+10=3x
(subract 2x from both sides)
x=10
Therefore, Arjun is 20 years old and Shreya is 10 years old :)

Step-by-step explanation:
Idk what ur asking but i tried to help
So to solve this problem, we can either do guess and check, or solve an equation.
Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.
So, to begin, let's define our unknown.
We can represent the number as "n"
So, 6 percent of "n" is equal to 270
To find a "percent" of a number, you need to multiply the number by the percentage.
So, 6 percent as a decimal is .06
This is because a percent is a fraction divided by 100 (6/100)

The number is 4,500
Step-by-step explanation:
since the coefficient is the same for the fist three they have the same equation.
the reason: there can only be one line that goes through one point with a specific coefficient.
