Richard wants to make a garden with a perimeter of 16 feet, and length of 4 feet. He solves for the width by subtracting 8 from
Ostrovityanka [42]

The equation that can be used to solve this is:

P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W

Further explanation:

Let

P\ be\ the\ perimeter\\L\ be\ the\ width\\W\ be\ the\ width

The equation for the perimeter will be:

P =2W+2L

Given

P = 16 feet

L = 4 feet

W = ?

Putting the values in the perimeter formula

16=2(4)+2W\\16=8+2W\\16-8= 2L\\8=2L\\L=\frac{8}{2}\\L=4\ feet

The equation that can be used to solve this is:

P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W

Write y=(- 3/4)x+3 in standard form using intregers
Daniel [21]
Y = (-3/4)x + 3
4y = 4 * [ (-3/4)x + 3 ] ... multiply both sides by 4
4y = 4*(-3/4)x + 4*3  ...... distribute
4y = -3x + 12 
4y + 3x = -3x + 12 + 3x .... add 3x to both sides
3x + 4y = 12

Answer: 3x + 4y = 12
