Answer:
25 pounds.
Step-by-step explanation:
The ratio is 8 pounds on earth is one pound on Venus. As the example shows 160 to 20. 160/8=20. This proves it. Then 200/8=25. There is your answer. :) Tell me if you need anything else.
B= 2
C= 3
D= 4
Answer:
`Option B.
Step-by-step explanation:
The given system of equations is
The graph of first equation is circle and the graph of second equation is a line.
We know that a line can intersect a circle at most 2 times. So, the greatest possible number of solutions is 2.
First equation can be rewritten as
It is the standard form of a circle , where (h,k) is center and r is radius.
In the above equation h=0,k=0 and r=3. It is a circle with radius 3 and centered at origin.
The second equation is
It is a linear equation.

Plot these points on a coordinate plane and connect them by a straight line.
From the below graph it is clear that the line and circle intersect each other at two points. So, the given system of equation have two solutions.
Therefore, the correct option is B.
Answer:
B
Step-by-step explanation:
Answer:
x=11.5
Step-by-step explanation:
18+6x=41+4x
Subtract 4x from each side
18+6x-4x=41+4x-4x
18+2x = 41
Subtract 18 from each side
18-18 +2x = 41-18
2x =23
2x/2 = 23/2
x =11.5
