The length of a rectangle is 4 less than three times it’s width. The perimeter is 72 feet. Find the dimensions of a rectangle
ratelena [41]

Answer:

Step-by-step explanation:

so let’s say x is the length.  Then the width will be 3x-4.  You add them together and multiply by two.  The perimeter is 72 so the equation equala 72.

Equation:

(x+3x-4)*2=72

(4x-4)*2=72

8x-8=72

8x=80

x=10

length:10

width:26

Solve for y Please help I need a tip
Gwar [14]

Answer:

y = 4

Step-by-step explanation:

Step 1: Write equation

9/4y - 12 = 1/4y - 4

Step 2: Solve for <em>y</em>

  1. Subtract 1/4y on both sides: 8/4y - 12 = -4
  2. Simplify: 2y - 12 = -4
  3. Add 12 to both sides: 2y = 8
  4. Divide both sides by 2: y = 4

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

9/4(4) - 12 = 1/4(4) - 4

9 - 12 = 1 - 4

-3 = -3
