Answer:
x = 9.25
y = 13.5
Step-by-step explanation:
area = 33
let length be y and width be x
2x - 5 = y
area of rectangle = length * breadth
(2x-5)(x)=33
2x²-5x=33
2x²-5x-33=0
solving quadratic equation
x = 9.25
y = 13.5
Convert "3/4 ton" into pounds. Use the identity 2000 lb = 1 ton.
2000 lb 1500 lb
Then [(3/4) ton] * ---------------- = ----------------
1 ton 1
Now divide 1500 lb by 4 lb 14 oz. Note that 4 lb 14 oz = 4 14/16 lb, or
4 7/8 lb, or 4.875 lb.
Then, divide 1500 lb by
4.875 lb
------------ to determine the number of bricks the truck can safely carry.
1 brick
This comes out to 1500/4.875 bricks, or approx. 307 bricks.
