If you have two numbers x, y. The geometric mean is: √xy
For 4 and x. Geometric Mean = √4x and this is equal to √6
√4x = √6 Square both sides. The square root disappears.
4x = 6
x = 6/4 = 3/2 = 1.5
The other number is 1.5.
I believe your answer is C
Answer:
x = 10
y = 25
Step-by-step explanation:
if you add the equations as they are then the 'y-term' is eliminated:
60x = 600
x = 10
substitute x=10 to find value of 'y':
40(10) + 4y = 500
400 + 4y = 500
4y = 100
y = 25
Check:
20(10) - 4(25) should equal 100
200 - 100 = 100
100 = 100
The relationship is that both of them are next to each other and there both and seperate places and value
