Answer:
The amount in the account after 7 years is $12,450
Step-by-step explanation:
To calculate the amount that will be in the account after 7 years, what we do is to simply add the interest to the principal.
Thus, we need to calculate the interest. Mathematically, the simple interest can be calculated using the formula below;
I = PRT/100
where P is the principal which is the amount deposited initially into the account = $10,000
R is the interest rate which is 3.5%
T is time which is 7 years
Plugging these figures, we have
I = (10,000 * 3.5 * 7)/100
I = $2,450
Thus the amount we have in the account which is interest + capital = 2,450 + 10,000 = $12,450

Step-by-step explanation:
Simplifying
3x + -1x + -5 = 2(x + 2) + -9
Reorder the terms:
-5 + 3x + -1x = 2(x + 2) + -9
Combine like terms: 3x + -1x = 2x
-5 + 2x = 2(x + 2) + -9
Reorder the terms:
-5 + 2x = 2(2 + x) + -9
-5 + 2x = (2 * 2 + x * 2) + -9
-5 + 2x = (4 + 2x) + -9
Reorder the terms:
-5 + 2x = 4 + -9 + 2x
Combine like terms: 4 + -9 = -5
-5 + 2x = -5 + 2x
Add '5' to each side of the equation.
-5 + 5 + 2x = -5 + 5 + 2x
Combine like terms: -5 + 5 = 0
0 + 2x = -5 + 5 + 2x
2x = -5 + 5 + 2x
Combine like terms: -5 + 5 = 0
2x = 0 + 2x
2x = 2x
Add '-2x' to each side of the equation.
2x + -2x = 2x + -2x
Combine like terms: 2x + -2x = 0
0 = 2x + -2x
Combine like terms: 2x + -2x = 0
0 = 0
Solving
0 = 0

This equation is an identity, all real numbers are solutions.
Answer:
Martina has 18,000
Step-by-step explanation:
- Set up the 4/5 the amount Tamara has as a proportion. 4/5 = x/20000
- Then cross multiply
- 4 * 20,000 = 80,000
- 80,000 = 5x
- Divide and get 16,000 (This is 4/5 of what Tamara has)
- Set up what Martina has as a proportion. 8/9 = 16,000/x
- Cross multiply 8x = 16,000 * 9
- 8x = 144,000
- Divide by 8
- 18,000 :)
