Speed= distance divided by time. The answer is 30, and im assuming miles per hour. Hope this helps
So 2/3=x/(3x+y)
multiply both sides by 3x+y
(2(3x+y))/3=x
(6x+2y)/3=x
multiply by 3
6x+2y=3x
subtract 6x form both sdies
2y=-3x
-3x=2y
the ratio of x to y is
-3:2
Answer:
$114,000
Step-by-step explanation:
Use formula
![I=P\cdot r\cdot t,](https://tex.z-dn.net/?f=I%3DP%5Ccdot%20r%5Ccdot%20t%2C)
where
I = interst
P = principal
r = rate
t = time
First, find the interst for 25 years:
I = unknown
P = $190,000
r = 0.03 (3% as decimal)
t = 25
![I_{25}=190,000\cdot 0.03\cdot 25=142,500](https://tex.z-dn.net/?f=I_%7B25%7D%3D190%2C000%5Ccdot%200.03%5Ccdot%2025%3D142%2C500)
Now find the interest for 5 years:
I = unknown
P = $190,000
r = 0.03 (3% as decimal)
t = 5
![I_5=190,000\cdot 0.03\cdot 5=28,500](https://tex.z-dn.net/?f=I_5%3D190%2C000%5Ccdot%200.03%5Ccdot%205%3D28%2C500)
The unpaid balance is
![I=I_{25}-I_5=142,500-28,500=114,000](https://tex.z-dn.net/?f=I%3DI_%7B25%7D-I_5%3D142%2C500-28%2C500%3D114%2C000)
2nd one maybe I’m not to sure srry
