Video Solution

Solution Steps

00:00 Solve
00:03 Division is also multiplication by the reciprocal
00:14 Negative times negative always equals positive
00:21 Negative times positive always equals negative
00:29 Let's factor 450 into factors 9 and 50
00:38 Negative times negative always equals positive
00:49 Let's simplify what we can
00:54 Let's solve 9 times 3
01:00 Let's group the factors
01:03 And this is the solution to the question

Step-by-Step Solution

To solve the given expression, we'll simplify it step-by-step:

  • Step 1: Simplify the fraction
    503\frac{50}{-3} simplifies to 503-\frac{50}{3}.
  • Step 2: Perform the division
    The expression 450:503-450:\frac{50}{-3} can be rewritten as 450×350-450 \times -\frac{3}{50} since division by a fraction is equivalent to multiplication by its reciprocal.
  • Calculate the multiplication
    450×350=450×350=450×0.06=27-450 \times -\frac{3}{50} = 450 \times \frac{3}{50} = 450 \times 0.06 = 27.
  • Step 3: Simplify the expression within parentheses
    The expression (3x)+(14)(-3x) + (-14) simplifies to 3x14-3x - 14.
  • Step 4: Combine all parts
    The complete expression (450:503)((3x)+(14))(-450:\frac{50}{-3}) - ((-3x) + (-14)) simplifies to 27(3x14)27 - (-3x - 14).
  • Simplify further
    This becomes 27+3x+14=41+3x27 + 3x + 14 = 41 + 3x.

Therefore, the solution to the problem is 41+3x 41 + 3x .

Answer

41+3x 41+3x
