I did this my sophmore year in highschool and I'm trying to remember lol. But first you add all the marbles together. 1+4+3. its eight. and since the marble was put back in this makes it an independant event. i believe the answer would be 2/8 considering that there isnt enough numbers to follow through with the equation of (P(a or b)=P(a)xP(b) . P is the probability and a and b are the variabls that represent the events. You would plug in the numbers of the probabilities into the equation, if you think the question calls for it. sorry it may not have been a staright up answer.
14 + 7 * 54 / 6 - 7
Use PEMDAS
There are no parenthesis nor exponents so move on to multiplying and dividing work left to right!
14 + 7 * 54 / 6 - 7
14 + 378 / 6 - 7
14 + 63 - 7
77 - 7
70 is your answer
You group the like terms together
6a+2a=24-8
8a=16
a=16÷8
a=2
A decrease means it is going into the negative direction on the number line.
This is represented by the integer -11.
