Solve <br><br> 0.6(10n + 25) = 10 + 5n ?
Pachacha [2.7K]

Answer: x=-5

<u>Simplify both sides of the equation</u>

(0.6)(10n)+(0.6)(25)=10+5n(Distribute)\\6n+15=10+5n\\6n+15=5n+10

<u>Subtract 5n from both sides</u>

6n+15-5n=5n+10-5n\\n+15=10

<u>Subtract 15 from both sides</u>

n+15-15=10-15\\n=-5

A teacher is four time as old as a student .in 20 years, the student 's age will be half of the teacher 's age. How old are they
notka56 [123]
Let the present age of student be x
Present of teacher will be 4x

After 20 years,
Age of student = x + 20
Age of teacher = 4x + 20

According to the given condition after 20 years,
x + 20 = (4x + 20)/2
x + 20 = 2x + 10
2x - x = 20 - 10
x = 10

So student's present age is 10 years while teacher's is 4 x 10 i.e 40 years.
