Answer:
Profit % =50%
Step-by-step explanation:
Cost of 50 kg = sh 4000
Selling price of 1kg = sh 120
Selling price of 50 kg = sh 6000
It is 0% Bc it’s not capital
D = 0.5 + 20x + 0.5v
Initial distance covered d1 = 0.5km
If she rode a bicycle for x hours at an average speed of 20 kilometers per hour, then her distance during thus period is,;
Speed = Distance/Time
Distance d2 = speed × time
d2 = 20x
If she ran for 0.5 hour at an average speed of v kilometers per hour, her distance this time will be;
Distance d3 = 0.5v
If her total distance is D, then;
D = d1+d2+d3
D = 0.5 + 20x + 0.5v
Hence an equation that relates D, x, and v is D = 0.5 + 20x + 0.5v

Answer:
Use the distributive property to write each expression as an equivalent algebraic expression:-
a.) 4(x + 5) = 4x + (4 x 5 ).
= 4x + 20 .
b.) 3(2x - 4) = 3 x 2x = 6x - (3 x -4 )
= 6x - 12 .
C.) -2(x - 6) = -2x - ( -2 x -6 ) .
= -2x - 12 .
