Step-by-step explanation:
pq = 3 - a√x
Making x subject
a√x = 3 - pq
√x = (3 - pq) / a
x = [ (3 - pq) /a ]²
Hope it will help :)
This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
There is probably a way to find this with an algebraic expression but i dont know how to, so i will use trial and error.
1(16)+2(17)=50
5(16)+6(17)=182
They made 17 forks and 16 spoons.
Given:
depreciation rate: 18%
Value of the car : 20,000
Age of the car : 4 years.
The depreciation is based on the current value of the car. Therefore, the amount of depreciation varies.

The current value of a car bought 4 years ago is 9,042.44
Beginning value : purchased amount on 1st year. then, ending balance of the previous year from 2nd year onwards.
Depreciation : Beginning value * depreciation rate
Ending value : Beginning value - depreciation
