When seen as a function, a relationship exists between a set of inputs and outputs.
The number of bricks in the chimney exists 900.
A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
Simply described, a function is an input-output connection where each input is coupled to exactly one output range, codomain, and domain are included in each function. A function exists generally denoted by f(x) where x exists the input.
Let x be the number of bricks in the chimney. The work done exists the rate multiplied by the time.
Using w = rt, we get
[tex]$x=\left(\frac{x}{9}+\frac{x}{10}-10\right) \cdot 5[/tex]
Expanding the above equation, we get
[tex]$\left(\frac{x}{9}+\frac{x}{10}-10\right) \cdot 5: \quad \frac{19 x}{18}-50$[/tex]
x = (19x / 18) - 50
Multiply both sides by 18
[tex]$x \cdot 18=\frac{19 x}{18} \cdot 18-50 \cdot 18[/tex]
Simplifying the above equation,
x × 18 = 19x - 900
Subtract 19x from both sides
x × 18 - 19x = 19x - 900 - 19x
Simplifying the above equation, we get
-x = -900
Divide both sides by -1
[tex]$\frac{-x}{-1}=\frac{-900}{-1}[/tex]
x = 900
Therefore, the value of x exists 900.
The complete question is:
Bricklayer Brenda would take nine hours to build a chimney alone, and bricklayer Brandon would take hours to build it alone. When they work together, they talk a lot, and their combined output decreases by bricks per hour. Working together, they build the chimney in hours. How many bricks are in the chimney?
