Apicture frame has a perimeter of 40 inches. its length is 2 inches greater than one-half its width. let w represent the width of the picture frame, and let l represent the length. which system of equations can be used to find the dimensions of the picture frame?

2l+2w=40
l=2+1/2w

2l+2w=40
l=1/2w-2

lw=40
l=1/2w-2

lw=40
l=2+1/2w

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
