We need to arrange the formula for l.
Take b to LHS,
![S-b=\dfrac{1}{2}Pl\\\\2(S-b)=Pl\ [\text{cross-multiplying}]\\\\l=\dfrac{2(S-b)}{P}](https://tex.z-dn.net/?f=S-b%3D%5Cdfrac%7B1%7D%7B2%7DPl%5C%5C%5C%5C2%28S-b%29%3DPl%5C%20%5B%5Ctext%7Bcross-multiplying%7D%5D%5C%5C%5C%5Cl%3D%5Cdfrac%7B2%28S-b%29%7D%7BP%7D)
So, the expression is 
for the slant height.
Answer: 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Step-by-step explanation:
Let x = Quantity of wooden blocks.
y = Quantity of plastic bricks.
As per given , we ahve
5x+10y=80 (i)
x+y=10 (ii)
Multiply 5 on both sides of (ii), we get
5x+5y=50 (iii)
Eliminate (i) from (iii), we get
5y=30
⇒ y= 6
Put y=6 in (ii), we get
x+6=10
⇒ x= 10-6= 4
Hence, 4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
