1.06(12.25 + x) = 19.08
12.25 + x = 19.08/1.06 = 18
x = 18 - 12.25 = 5.75
Therefore, the cost of the cat food is $5.75

Answer.....15ft by 12ft
Explanation:
Area = Length × Width
180 = LW....make W the subject of formula
;W = 180/L
Perimeter = 2L + 2W
54 = 2L + 2(180/L)...sub W with the formula above...
then simplify the equation and obtain...
2L^2 - 27L + 180 = 0....then solve using the quadratic formula....then obtain..
;L = 15ft....after obtaining L = 15...then substitute into the W = 180/L equation...
where W = 180/15 = 12ft
there you have...Length = 15ft and Width = 12ft
Please be more specific and what are the measurements as in height and radius or diameter.
Answer:
x = 2
Step-by-step explanation:
3.x + y = 11 (eq 1)
Y = x + 3 (eq 2)
sub 2 into 1
3x + x + 3 = 11
4x + 3 = 11
4x = 8
x = 2
