Kelly is x years old. Mike is 2 years older than twice Kelly's age. The sum of Kelly and Mike's ages is 26. How old is Mike?
To find out how old Mike is, we need to first find out Kelly's age.
Let's represent Kelly's age as x.
According to the information given, Mike is 2 years older than twice Kelly's age. So, we can write Mike's age as 2x + 2.
The sum of Kelly and Mike's ages is 26, so we can set up the equation:
x + (2x + 2) = 26
Simplifying the equation, we get:
3x + 2 = 26
Subtracting 2 from both sides, we get:
3x = 24
Dividing both sides by 3, we find:
x = 8
So, Kelly is 8 years old.
Now, we can find Mike's age by substituting 8 into the expression for Mike's age:
2x + 2 = 2*8 + 2 = 16 + 2 = 18
Therefore, Mike is 18 years old.
m = 2 + 2x
x + m = 26
so
x + 2 + 2x = 26
3 x = 24
x = 8
so
m = 2 + 16 = 18
Damon is correct! :)
A bank has two plans for checking accounts. With plan A the charge is $7.50 a month with no fee for each check. With plan B the charge is $3 a month plus an additional 20 cents for each check written.What is the least number of checks a customer must write each month in order for plan A to cost less than plan B?
when 750 = 300 + 20 c
20 c = 450
c = 22.5 so 22
