First distribute -4 to all terms within the parenthesis

-4(x) = -4x

-4(1) = -4

-4x - 4 + 5 = 17

Simplify. Combine like terms

-4x (-4 + 5) = 17

-4x + 1 = 17

Isolate the x. Do the opposite of PEMDAS. Note the equal sign. What you do to one side you do to the other.

Subtract 1 from both sides

-4x + 1 (-1) = 17 (-1)

-4x = 16

Divide -4 from both sides

-4x/-4 = 16/-4

x = 16/-4

x = -4

-4 is your answer

hope this helps

-4(x + 1) + 5 = 17

Distribute -4 inside the parentheses.

(-4x - 4) + 5 = 17

Combine like terms (-4 + 5).

-4x + 1 = 17

Subtract 1 from both sides.

-4x = 16

Divide both sides by -4.

x = -4

Here’s my dilemma, I can accept a $1000 bill or play a game ten times. For each roll of the single die, I win $500 for rolling 1
Aloiza [94]

Answer:

you should accept the $1,000 bill

Step-by-step explanation:

Given the information:

  • $500 for rolling 1 or 2
  • $400 for rolling 3
  • lose $300 for rolling 4,5,6

P (rolling 1 or 2) = 1/6 + 1/6 = 2/6 = 1/3

P (rolling a 3) = 1/6

P (rolling 4 or 5 or 6) = 3/6 = 1/2

Hence, the expected value for 1 time is:

E = (1/3)*500 + (1/6)*400 - (1/2)*300

E = $166 + $66 - $150

E = $82

Expected value is linear so if you roll the die 10 times, expected value is: 10*82 = $820

The expected value is $82, meaning you should accept the $1,000 bill
