1.) in a litter of 7 kittens each kitten weighs less than 3.5 ounces find all of the possible values of the combined weights of the kittens
2.) to cover a rectangular region of her yard penny needs atleast 170.5 square feet of sod the length of the region is 15.5 feet what are the possible widths of the region

Here's 1.)
-Use w to symbolize the weight of kittens. Given by the statement "each kitten weighs less than 3.5 ounces" we know that:-
1*w < 3.5 
-You can multiply both sides of the inequality by 7 to determine the total weights: 7*(1*w) < 7*(3.5) 7*w < 24.5
-Since there are 7 kittens, the combined weight of the kittens is 7w, therefore the above expression could be read as "The combined weight of the kittens is less than 24.5 ounces"

Here's 2.)

width = 170.5/15.5 = 11 ft
Explanation:
area = 170.5 sq ft.
length = 15.5 ft.
width = 170.5/15.5 = 11 ft
