Step-by-step explanation:
We want to find k when y=kx
2y = 20x
Divide each side by 2
2y/2 =20x/2
y = 10x
The constant of proportionality is 10

Answer:
66560 pairs
Step-by-step explanation:
let the number of pairs of boots the company makes in 260 days = X
1day -----------------256pairs
260days-------------X
cross multiplying
1×X = 260×256
X= 66560
therefore, in 260days, he makes 66560 pairs
Step-by-step explanation:
V = h × w × l
7650 = 9 × 25 × l
So,
l = 7650 ÷ 9 ÷ 25
l = 850 ÷ 25
l = 34
For the final, the length is 34.
