Andrew has six fewer coins than Casey. Bob has two more than twice as many coins as Andrew. Altogether, they have 504 coins. How many coins does Bob have?

Answers

Answer 1

Answer: Andrew: x - 6
      Bob: 2x - 12
Casey: x

(x - 6) + (2x - 12) + x = 504
(x + 2x + x) + (-6 - 12) = 504
      4x - 18 = 504
      + 18   + 18
       4x = 522
      4    4
   x = 130.5

What is the solution to the equation 4.7x+3.8=13.2

Answers

Simplifying4.7x + 3.8 = 13.2Reorder the terms:3.8 + 4.7x = 13.2Solving3.8 + 4.7x = 13.2Solving for variable 'x'.Move all terms containing x to the left, all other terms to the right.Add '-3.8' to each side of the equation.3.8 + -3.8 + 4.7x = 13.2 + -3.8Combine like terms: 3.8 + -3.8 = 0.00.0 + 4.7x = 13.2 + -3.84.7x = 13.2 + -3.8Combine like terms: 13.2 + -3.8 = 9.44.7x = 9.4Divide each side by '4.7'.x = 2 so 2 is your answer hope this helps :)
