Math Problem Statement

Solve the following inequalities: 1) 66 > 2(5x + 3), 2) -4x - 5(x + 6) <= -66, 3) 2 + 4(3 - 2x) >= 6, 4) 2(2x + 2) + 2(2x + 5) <= 14

Solution

I can see the inequalities from the image you uploaded. Let me go through each one and solve them step-by-step:

Problem 11: 66>2(5x+3)66 > 2(5x + 3)

  1. Distribute the 22:
    66>2(5x+3)66 > 2(5x + 3)
    66>10x+666 > 10x + 6

  2. Subtract 6 from both sides:
    60>10x60 > 10x

  3. Divide by 10:
    6>x6 > x
    or
    x<6x < 6


Problem 12: 4x5(x+6)66-4x - 5(x + 6) \leq -66

  1. Distribute the 5-5:
    4x5(x+6)66-4x - 5(x + 6) \leq -66
    4x5x3066-4x - 5x - 30 \leq -66

  2. Combine like terms:
    9x3066-9x - 30 \leq -66

  3. Add 30 to both sides:
    9x36-9x \leq -36

  4. Divide by 9-9 (reverse the inequality):
    x4x \geq 4


Problem 13: 2+4(32x)62 + 4(3 - 2x) \geq 6

  1. Distribute the 44:
    2+128x62 + 12 - 8x \geq 6

  2. Combine like terms:
    148x614 - 8x \geq 6

  3. Subtract 14 from both sides:
    8x8-8x \geq -8

  4. Divide by 8-8 (reverse the inequality):
    x1x \leq 1


Problem 14: 2(2x+2)+2(2x+5)142(2x + 2) + 2(2x + 5) \leq 14

  1. Distribute the 22 on both terms:
    4x+4+4x+10144x + 4 + 4x + 10 \leq 14

  2. Combine like terms:
    8x+14148x + 14 \leq 14

  3. Subtract 14 from both sides:
    8x08x \leq 0

  4. Divide by 8:
    x0x \leq 0


Would you like a more detailed breakdown or explanation for any of these? Here are 5 related questions to deepen understanding:

  1. How do we reverse inequality signs when dividing by a negative number?
  2. What is the difference between solving an equation and an inequality?
  3. How can we represent these solutions on a number line?
  4. What would happen if we change the inequality symbols in these problems?
  5. Can inequalities have multiple solutions, and how are they represented?

Tip: Always remember to reverse the inequality sign when you multiply or divide both sides by a negative number.
