Answer:

Current \ price = 609000\\\\Let \ the \ original \ price \ be = x\\\\\% increase = 5 \% \ of \ x = \frac{5}{100} \times x = \frac{5x}{100}\\\\Price \ after \ increase, current\ price = \frac{5x}{100} + x\\\\

=> 609000 = \frac{5x}{100} + x\\\\=>609000 = \frac{105x}{100}\\\\=> x = \frac{609000 \times 100}{105}\\\\x = 580000

Therefore original price = $580,000

Hi this is for texaschic101 mainly but anyone else is fine too.
Makovka662 [10]
Because the two angles on the right add to 180 degrees, we can create this system:

(2x + 25) + y = 180

We can also prove that 3x = 2x + 25, which, when solved, shows that x = 25. 

When plugged in to the original equation, we find that y = 105 degrees.

Faris's gas tank is 1/10 full. After he buys 24 liters of gas, it is 2/5 full. How many liters can Faris's tank hold?
Arisa [49]

Answer:

80 liters

Step-by-step explanation:

24 liters is the difference between 2/5 full and 1/5 full.

Let x = number of liters in full tank.

2/5 x - 1/10 x = 24

4/10 x - 1/10 x = 24

3/10 x = 24

1/10 x = 8

x = 80

Answer: 80 liters
