Jason has a rectangular pool with a perimeter of 90 feet. the length of his poll is twice its width. what are the length and width, in feet, of jasons pool?

length: 30 ft

width: 15 ft

Step-by-step explanation:

The sum of length and width is half the perimeter, 45 ft.

The ratio of length to width is 2 : 1, so the sum in "ratio units" is 2+1 = 3. That is, each "ratio unit" stands for 45 ft/3 = 15 ft of actual length.

Jason's pool is ...

length : width = 2·15 ft : 1·15 ft = 30 ft : 15 ft

Jason's pool is 30 ft long and 15 ft wide.

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular

124 large total

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct
