There are 75 marbles in a bin and 40% of the marbles are blue how many blue marbles are in the bin

30 blue marbles

Step-by-step explanation:

for things l;ike this where ite percentage is in the tens place I like finding what 10% is, I do this by dividing it by 10, so, 75/10=7.5. SO then you want to multiply that by four because 10% times 4 = 40% which is the equation you need so (this part isnt needed but its more visually descriptive)

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

your question is incomplete, write all the numbers in the sequence that it tells you.
