Answer:
2/3
Step-by-step explanation:
To find the constant of proportionality in the set of data apply the formula for slope where;
m= Δy/Δx
Taking values such as {3,2} and {6,4} then
m= 4-2 / 6-3
m= 2/3
Answer:
x = 6.33, y = 3.67 to the nearest hundredth.
Step-by-step explanation:
3x - 3y - 2 = 6
4x - 5y - 3 = 4 Simplifying these 2 equations:
3x - 3y = 8 (A) Multiply by by 5
4x - 5y = 7 (B) Multiply by by -3
15x - 15y = 40
-12x + 15y = -21 Adding:
3x = 19
x = 19/3 = 6.33
so y = (8 - 3 *6.33 ) / - 3 (from Equation B )
= 3.67.
406.25
And for extra info to get to 406.25 you can just take 19,500 and divide it by 48
Answer:
10%
Step-by-step explanation:
Given: CP of lemon is $600.
3/4 of lemon sold at 20% loss
Remaining lemon at 20% gain.
Considering the quantity of lemon remain constant.
Cost price of 3/4 of lemon= 
As given, 3/4 of lemon sold at 20% loss.
∴ Selling price of 
Selling price= 
Hence, selling price of 3/4 lemon is $360.
Now, the cost price of remaining lemon 
∴ The cost price of
As given, remaining 
∴ Selling price of 
Selling price of 
Hence, selling price of 1/4 lemon is $180
Loss\profit percent= 
∴ Loss\profit percent= 
Hence, the loss percentage is 10%
