First equation 
L.H.S = 4x -0.25y 
so it doesn't equal the R.H.S 

2nd equation 
R.H.S = 15q + 3qr 
so it doesn't equal the L.H.S 

3rd equation 
R.H.S = -30m -60n 
so R.H.S doesn't equal L.H.S 

4th equation 
L.H.S = -16a +4 
so L.H.S equal R.H.S 

The answer is D

sergij07 [2.7K]

Mr. Inahurry sold his house for $27,000, which is a 10% loss over what he originally paid for it. What did he pay for the house
Ainat [17]

Answer: $30,000

Step-by-step explanation:

If Mr. Inahurry had a 10% loss, it means that he paid X for the house and only got back 90% (100% - 10%) of what he paid.

This way X . 90% = 27,000

               X . 0.90 = 27,000

               X = 27,000/0.9

               X = 30,000

Counter-proof: 30,000 . 10% = 30,000 . 0.10 = 3,000

                          30,000 - 3,000 = 27,000

How do you do this question?
katen-ka-za [31]

Answer:

0

Step-by-step explanation:

∫ sin²(x) cos(x) dx

If u = sin(x), then du = cos(x) dx.

∫ u² du

⅓ u³ + C

⅓ sin³(x) + C

Evaluate between x=0 and x=π.

⅓ sin³(π) − ⅓ sin³(0)

0
