Three teachers are needed for 70 children, that is:
3 = 70..............  equation 1.
 For 14,700 children, Y number of teachers are needed, thus, we have
Y = 14,700...........equation 2.
3 = 70
Y = 14, 700.
Cross multiplying we give us,
3 * 14, 700/70 * Y.
44,100/70Y
Y = 630.
Thus, 630 teachers are needed to teach 14,700 children.
The district already have 612 teachers, so they need 630 - 612 = 18. 
So, the district needs 18 more teachers.

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

-7 - 3x = 1x + 4(2 + x)

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

  1. Distribute 4:                                                                                                    -7 - 3x = x + 8 + 4x
  2. Combine like terms:                                                                                       -7 - 3x = 5x + 8
  3. [Addition Property of Equality] Add 3x on both sides:                                -7 = 8x + 8
  4. [Subtraction Property of Equality] Subtract 8 on both sides:                      -15 = 8x
  5. [Division Property of Equality] Divide 8 on both sides:                               -15/8 = x
  6. Rewrite/Rearrange:                                                                                        x = -15/8
