Answer:
K=13,5
y=13,5x, x=numbers of hours
Step-by-step explanation:
To find the proporcionality constant, divide the number of milles traveled in given time.
K=54/4=67,5/5=81/6=13.5 and the equation that describes the relationship is y=13,5x
Answer:
30 in, 0.5 m, 1.25 ft, 17 cm
Width of a rectangle is half its length:
2w = l
Perimeter is 36
2w + 2l = 36
Plug first equation into second (substitution)
2w + 2(2w) = 36
2w + 4w = 36
6w = 36
w = 6
Plug back into first equation to solve for l
2(6) = 12 = l
