If 10 skeins makes 4 scarves than if you multiply the skeins by 2 (20 skeins) it would make 8 scarves. There for dividing the skeins by 2 (5 skeins) it would make 2 scarves. So adding 20 skeins and 5 skeins you would get 10 scarves total
Answer:

Answer:
y = 3x
Step-by-step explanation:
A proportional relation has the equation ...
y = kx
To write the desired equation, you need to know the value of k. That can be found from the given information:
for x = 2, y = 6
6 = k·2
3 = k . . . . divide by 2
Now, we know the equation can be written ...
y = 3x
Answer:
d^2 = 12^2 + 5^2 = 169
d = 13
r = d/2 = 6.5
A = pi·6.5^2 = 132.73 cm²
