Answer:
{x,y} = {5,6}
Step-by-step explanation:
// Solve equation [1] for the variable x
[1] x = y - 1
// Plug this in for variable x in equation [2]
[2] 2•(y -1) - y = 4
[2] y = 6
// Solve equation [2] for the variable y
[2] y = 6
// By now we know this much :
x = y-1
y = 6
// Use the y value to solve for x
x = (6)-1 = 5
The answer for this would be 10a^5/3
Answer:
$227
Step-by-step explanation:
First we can add up the withdrawals(63, 74, and 39) which is 176. We can then subtract 176 from 212 to get 36.
So, after the withdrawals Steven has 36 dollars.
We can add the deposits together to get 191. We can then add 191 to 36 to get 227.
Ok so <span>Interest = Principle * rate * time
P = 10,000
R = 3% = 0.03
T (we need to solve for t
I = 3600
now we sub..
3600 = (10,000)(0.03)(t)
3600 = 300t -- divide both sides by 300
3600/300 = t
12 = t
check..
I = prt
3600 = (10000)(0.03)(12)
3600 = (300)(12)
3600 = 3600 (correct)
It would take 12 years</span>
