Step-by-step explanation:
To cover a rectangular region of her yard, Penny needs at least 217 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?
L=length=15.5 ft; W=width; A=area=>217 sq ft
L*W=>217 sq ft Divide each side by L
W=>217 sq ft/L
W=>217 sq ft/15.5 ft=>14 feet

Answer:
Step-by-step explanation:
Let's start with an equation like 2x+4=10. We have to isolate x to get an answer. We go for the number without the variable first.
2x+4=10
Subtract 4 from both sides.
2x+4-4=10-4
2x=6
Divide by 2.
2/2=6/2
x=3
There you go!
Rational because it can be written as a ratio (fraction)
There is 16 ounces in a pound, so you do 16 x 6 which is equal to 96
