Answer:

$4.6

Step-by-step explanation:

Use 18.40 and 80. if $18.40 is 80 feet, divide 18.40 by 4 to get 4.60. Now you know that you got 4.60, see if you can add 4.6 four times to get to 18.4. (You can.) So, 20 feet is $4.60 or $4.6.

Answer:

x = 18

Step-by-step explanation:

Given:

  • a = 2x +3
  • b = 4x - 7

Finding x for which 3b = 5a:

  • 3b = 5a
  • 3(4x - 7) = 5(2x + 3)
  • 12x - 21 = 10x + 15
  • 12x - 10x = 15 + 21
  • 2x = 36
  • x = 36/2
  • x = 18
