Answer:

Step-by-step explanation:
Let be "s" the length in meters of the short piece and "l" the lenght in meters of the long piece.
Set up a system of equations:

Apply the Substitution Method to solve the system. Substitute the second equation into the first equation and solve for "l":

Susbstitute the value of "l" into the second equation in order to find the value of "s". This is:

45 should be the answer for that specific question.
3(4x+5)+2
3•4x=12x
5•3=15+2=17
Answer= 12x + 17
507/17576 or 0.0288
you take all the probabilities separate then multiply them all together. Then Simplify
