I think it would be 150....
3 units + 1 unit = 4 units (the sum of 2nd and 3rd)
4 units + 4 units = 8 units (sum of all properties)
*The other 4 units comes from the first property as the first property's value is the same as the sum of the 2nd and 3rd.*
8 units = $560 000
1 unit = $560 000÷8 = $70 000 (3rd)
3 units = 3x$70 000= $210 000 (2nd)
$210 000 + $70 000=$280 000 (1st)
Ans:
1st property costs $280 000.
2nd property costs $210 000.
3rd property costs $70 000.
Answer: c) -4
Step-by-step explanation:
Get the variables on one side of 3x+y=-2x+8 and the constants on another side:
3x+y=-2x+8
(3x+y)+2x=(-2x+8)+2x
5x+y=8
Now, multiply 5x+y=8 by -2:
-2(5x+y=8)
-10x-2y=-16
Add this equation to -3x+2y=-10:
(-10x-2y=-16)+(-3x+2y=-10)
-13x=-26
x=2
Plug x=2 into -3x+2y=-10:
-3(2)+2y=-10
-6+2y=-10
2y=-4
y=-2
Therefore, (2, -2) is the solution to the system of equations, so xy=(2)(-2)=-4
Answer:
h = a/4
Step-by-step explanation:
h = a/4 has already been solved for h; there is nothing left to do here.
Answer:
(choice D)
Neither is the answer for the question you asked becaure x - y = 0
