Answer:
2
3
1
4
Step-by-step explanation:
1 = 2.83
2 = -3.75
3 = 2.25
4 = 3
The right answer for the question that is being asked and shown above is that:
x = k (1/y)
k = xy
x1y1 = x2y2
8*10 = 6y2
80 = 6y2
y2 = 40/3
So the answer is 40/3
<span>X varies inversely with y and x = 8 when y = 10, what is the value of y when x=6</span>

Step-by-step explanation:
I think you mean
Since the variable parts are the same, the terms are like terms and can be combined together.
Answer:
x=closest to 12m
Step-by-step explanation:
Answer:
8 ten dollar bills
20 fifty dollar bills
Step-by-step explanation:
x = number of 10 dollar bills
y = number of 50 dollar bills
x+y = 28
10x+50y = 1080
Multiply the first equation by -10
-10x -10y = -280
Add this to the second equation
-10x -10y = -280
10x+50y = 1080
-----------------------
40y = 800
Divide by 40
40y/40 = 800/40
y = 20
Now find x
x+y =28
x+20 = 28
x = 28-20
x= 8
