ANSWER:
As we know, diagonals of parallelogram (||gm) bisect each other.
So, AE = EC
2x - 10 = 8x - 70
2x - 8x = - 70 + 10
- 6x = - 60
x = 10
Answer:
x = 1.5
y = 0
Step-by-step explanation:
10x + 5(2x - 3) = 15
10x + 10x - 15 = 15
20x - 15 = 15
20x = 30
x = 1.5
y = 2(1.5) - 3
y = 3 - 3
y = 0
Check:
10(1.5) + 5(0) = 15
15 + 5(0) = 15
15 + 0 = 15
15 = 15
Let's say the APR is 5%. That means you get 5% of your balance back every year. The $100 balance would get $5 back, the $500 balance would get $25 back, and the $1000 balance would get $50 back. Therefore, all of the balances would take the same amount of time to double, and it would take all of them 20 years.
$5*20 years=$100
$25*20 years=$500
$50*20 years=$1000
