-Dominant- [34]

Answer:

64 feet.

Step-by-step explanation:

From the question given, we can see that the answer has been done half way.

Now, the concluding part can be obtained as follow:

52/78 = x/96

Cross multiply

78 × x = 52 × 96

78x = 4992

Divide both side by 78

x = 4992/78

x = 64 feet

Therefore, the distance 'x' between the lions and monkeys is 64 feet.

<u>Pre-Algebra</u>

Distributive Property

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

1/2(8x - 4) = 2x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Distributive Property] Distribute 1/2:                                                              4x - 2 = 2x
  2. [Subtraction Property of Equality] Subtract 2x on both sides:                      2x - 2 = 0
  3. [Addition Property of Equality] Add 2 on both sides:                                    2x = 2
  4. [Division Property of Equality] Divide 2 on both sides:                                  x = 1
