X-5/-2 = x-1/-3 Explain how you found your answer please!!!
AleksAgata [21]
( x-5)/-2=(x-1)/-3
Cross multiply
-3(x-5)=-2(x-1)
Distribute
-3x +15 = -2x +2
Add 2x to both sides
-x +15 = 2
Subtract 15 from both sides
-x = -13
x=13

Ralph Chase plans to sell a piece of property for ​$170000. He wants the money to be paid off in two waysminusa ​short-term note
PSYCHO15rus [73]

Answer:

Amount of short term note = $90,000

Amount of long term note = $80,000

Step-by-step explanation:

Data provided in the question:

Total amount = $170,000

Interest rate of short term note = 10%

Interest rate in long term note = 8%

Total annual interest paid = $15,400

Now,

Let the amount of short term interest be 'x'

thus,

amount of long term interest will be ($170,000 - x)

also,

Interest on short term note + Interest on long term note = Total interest

or

⇒ 0.10 × x + 0.08 × ($170,000 - x) = $15,400

or

0.1x + $13,600 - 0.08x = $15,400

0.02x = $15,400 - $13,600

or

0.02x = $1,800

or

⇒ x = $90,000

Hence,

Amount of short term note = $90,000

Amount of long term note = $170,000 - $90,000 = $80,000
