Answer:
y=-1/3x+10/3
Step-by-step explanation:
Given that the diameter of a human hair
Given that the diameter of a spider's silk
Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk.
To find that we just need to subtract the given numbers.
Since powers are not same so let's make them equal
now we can easily subtract the coefficients that is 3 from 9
Hence final answer is .
You can make a proportion
<em>Cross multiply</em>
8 × 6 = 48
<em>Now, divide 48 by 9</em>
48 ÷ 9 = 48/9
x = 48/9
x=number of days the river decreased
3x=total number of inches river decreased
3(7)=total
21=total number of inches river decreased
