“X” is the independent valuable and “Y” is dependent.
Answer:
r=d/t
Step-by-step explanation:
just divide by t to isolate r
Answer:
Normal speed = 711.11 km/h (Approx)
Step-by-step explanation:
Assume;
Normal speed = x
New speed = x - 25% of x = 0.75 x
Time taken = t
New time taken = t + 1.5 hour
Total distance
Computation:
Total distance = 3,200 km
Speed = Distance/Time
x = 3200 / t
t = 3200/x
so,
0.75 x = 3200 / (t+1.5)
0.75 x = 3200 / (3200/x+1.5)
0.75 x = 3200 / [(3200 + 1,5x)x]
x = 711.11 km/h
Normal speed = 711.11 km/h (Approx)
Answer:
x=24,50n+30,00m
Step-by-step explanation:
In this equation n stands for the total amount of shirts sold and m for the total amount of jeans sold.
