Answer:

x=-1/6

Alternate form

x=-0.16, x=6^-1

Step-by-step explanation:

3(4-x)=13+3x

Distribute 3 through the parentheses

12-3x=13+3x

Move the variable to the left-hand side and change its sign

12-3x-3x=13

-3x-3x=13-12

collect like terms

-6x=13-12

-6x=1

Divide both sides of the eqation by -6

x=-1/6

Alternate form

x=-0.16, x=6^-1

Plzzzzzzzz! A suitcase lock has a code 4 symbols long. The symbols on the lock are a star, a square, a circle, a triangle, a lin

Answer:

                \dfrac{1}{30}

Step-by-step explanation:

6 symbols and 4-symbol code so number of combinations wich doesn't contain the same symbol twice would be:

6•5•4•3 = 360

If code starts with a star followed by triangle that means only one posibility for first two symbols and code doesn't containing the same symbol twice means that left 4 symbols for next two.

So number of combinations of code starting with a star followed by triangle and doesn't containing the same symbol twice will be:

1•1•4•3 = 12

The probability that a randomly chosen code starts with a star followed by triangle and doesn't contain the same symbol twice:

\dfrac{1\cdot1\cdot4\cdot3}{6\cdot5\cdot4\cdot3}=\dfrac{1\cdot1}{6\cdot5}=\dfrac{1}{30}
