<span>W=kr^3
1.20=8k
=> k = .15
So, W = .15r^3
When r=3 inch, W = .15*27 = 4.05 pounds
i hope this helps</span>
Answer:
x=5
Step-by-step explanation:
All we have to do for this equation is cross multiply. This means we multiply 7 and 5 together and 5 and x+2 together. This will make the equation 35=5(x+2). Simplify this to get 35=5x+10. Subtract 10 from both sides to get 5x=25. You want to isolate x so you have to divide both sides by 5. This will make the equation x=5.
