This is the answer 6x^2+15x+9
Answer:
C
Step-by-step explanation:
2.88*2.2=6.336, which is approximately 6.34.
X = first venture, y = second venture, z = third venture
x + y + z = 15,000
x + z = y + 7000
3x + 2y + 2z = 39,000
these are ur equations.....
x + y + z = 15,000
x - y + z = 7000
--------------------add
2x + 2z = 22,000
x + y + z = 15,000....multiply by -2
3x + 2y + 2z = 39,000
-------------------
-2x - 2y - 2z = - 30,000 (result of multiplying by -2)
3x + 2y + 2z = 39,000
------------------add
x = 9,000
2x + 2z = 22,000
2(9000) + 2z = 22000
18,000 + 2z = 22000
2z = 22000 - 18000
2z = 4000
z = 4000/2
z = 2,000
x + y + z = 15,000
9000 + y + 2000 = 15,000
11,000 + y = 15,000
y = 15,000 - 11,000
y = 4,000
first venture (x) = 9,000 <==
second venture (y) = 4,000 <==
third venture (z) = 2,000 <==
I believe it's 7.5 but I could be wrong.
Answer:
Data Set 1: 20
Data Set 2: 25
Step-by-step explanation:
Range = maximum value - minimum value
Range of Data Set 1:
Maximum value of data set 1 = 40
Minimum value of data set 1 = 20
Range of Data Set 1 = 40 - 20 = 20
Range of Data Set 2:
Maximum value of data set 2 = 60
Minimum value of data set 2 = 35
Range of Data Set 2 = 60 - 35 = 25
