Answer:
$1000
Step-by-step explanation:
We can form an equation for Clayton's account: C = 500 + 10x
We can form an equation for Clayton's account: J = 400 +12x
(where x is the number of days)
When the two accounts will contain the same amount, it means: C = J
<=> 500 + 10x = 400 +12x
<=> x =50
After 50 days, there accounts will be balance. Then, we substitue x into any of the 2 equation to find out the amount: 500 + 10(50) = $1000

Answer:
C. 15
Step-by-step explanation:
1. First, let's solve the system of equations;
Solve -m - n = 5 for m.
Substitute -n - 5 for m in m - n = -3.
Substitute -1 for n in m = -n - 5.
2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.
Therefore, the answer is C. 15!
