Answer: 21 Nickels
21 dimes
8 pennies
Step-by-step explanation:
Jamie's age is n. (given)
Brian's age is 2n. (given)
Half of Brian and Jamie's present age is (n +2n)/2 = 3n/2.
Let m represent Morgan's age now. Then
... m + 8 = 2 + 3n/2 . . . . . in 8 years, Morgan's age will be 2 more than ...
Subtract 8 to find Morgan's present age:
... m = 3n/2 - 6 . . . . Morgan's present age
It is b*h*l
Which 3 is height
9 is length
And 6 is width
The answer is C 162
Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation 4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16 there is no variable to multiply with the LHS equation
Solution:
4 (x-3)=16
4x - 12 = 16
4x = 16 + 12
4x = 28
x = 7
4x - 3 = 16
4x = 16 + 3
4x = 19
x = 19/4
x = 4.75
Answer:
He will have $39,750 at the end of five years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
