<u>Proportional relationship equation:</u>
- y = kx, where k- constant of proportionality
<u>Use the given point to work out the value of k:</u>
<u>In our case the equation is:</u>
- v = 5.6m, where v- volume, m- mass

Answer:
t =log(20) / 0.3 = 10*log(20) / log(1,000) - years - when the tree will have 100 branches.
Step-by-step explanation:
100 = 5 * 10^(0.3t), solve for t
Divide both sides by 5:
20 =10^(0.3t)
Take the log of both sides:
0.3t =log(20)
Divide both sides by 0.3:
Multiply the RHS by 10 / 10
t =log(20) / 0.3 = 10*log(20) / log(1,000) - years - when the tree will have 100 branches.
Let this number be x. The next number is (x+1). And their sum is 57. Then, we have to solve this equation x+x+1=57
