Answer:
2% profit
Step-by-step explanation:
x = price
50kg = 50x
30kg => 35x
20kg => 16x
35x + 16x = 51x
51x - 50x = x
50x .............. 100%
x ...................... p%
p = 1×100/50 = 100/50 = 2%
Geez that is real complicated sorry I’m not sure just go with your gut
Answer:
y =
x²
Step-by-step explanation:
Given that y and x² are directly proportional then the equation relating them is
y = kx² ← k is the constant of proportion
When x = 2
y = k × 2² = 4k
When x = 5
y = k × 5² = 25k
Then
25k - 4k = 20 ( difference between values is 20 )
21k = 20 ( divide both sides by 21 )
k = 
y =
x² ← equation of proportion
The answer would be 71.45
Answer:

/3
y+3
Step-by-step explanation:
be more specific and space out the equations next time please, i didn't know what you wanted me to do. but i solved them.
brainliest please?
