D what is joeys and martinas current ages
First Equation
STEP 1: Move the variable to the right side and change its sign
3x=8-y
STEP 2: Divide both sides of the equation by 3
x=8/3 - y/3
STEP 3: Write all numerators above the common denominator
x=8-y/3
THE FINAL ANSWER IS:
x=8-y/3
Second Equation
STEP 1: Move variable to the right side and change its sign
-x= -10+2y
STEP 2: Change the signs on both sides of the equation
x=10-2y
THE FINAL ANSWER IS:
x=10-2y

Answer:
$49560
Explanations:
The amount deposited is the principal
The principal, P = $24,000
Interest rate, r = 7.25% = 7.25/100 = 0.0725
Time, t = 10 years
Since the interest is compounded continuously, the amounte^ formula is given as:
![A\text{ = P}\times\text{e}^{rt}](https://tex.z-dn.net/?f=A%5Ctext%7B%20%3D%20P%7D%5Ctimes%5Ctext%7Be%7D%5E%7Brt%7D)
Substitute P = 24000, r = 0.0725, and t = 10 into the formula above:
![\begin{gathered} A\text{ = 24000}\times e^{0.0725(10)} \\ A\text{ = 24000}\times e^{0.725} \\ A\text{ = }24000\text{ }\times\text{ }2.065 \\ A\text{ = }49560 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%5Ctext%7B%20%3D%2024000%7D%5Ctimes%20e%5E%7B0.0725%2810%29%7D%20%5C%5C%20A%5Ctext%7B%20%3D%2024000%7D%5Ctimes%20e%5E%7B0.725%7D%20%5C%5C%20A%5Ctext%7B%20%3D%20%7D24000%5Ctext%7B%20%7D%5Ctimes%5Ctext%7B%20%7D2.065%20%5C%5C%20A%5Ctext%7B%20%3D%20%7D49560%20%5Cend%7Bgathered%7D)
