Answer: The retort to the peculiar proposed interrogate is definitively identified as ‘Joint Variation’, interchangeably acknowledged as ‘Combined Variation’.
Step-by-Step Explanation:
Given the mathematical statement,
Y = 4x^3z^3
Such coherently demonstrates the principle of a foreign variable, ‘y’, which whom varies directly as the product of at least two distinct or distinguishable quantities occur.
The mentioned is the precise definition of Joint Variation, where ‘y’ is jointly proportional to the product of the minimum agglomerate of two quantities, whilst a presence of a nonzero constant, k.

<h2>A can complete the work in 7*6 hrs = 42 hrs.
</h2><h2>
</h2><h2>A can complete in 1 hr = 1/42 part.
</h2><h2>
</h2><h2>B can complete the work in 7*8 hr = 56 hrs.
</h2><h2>
</h2><h2>A&B together do in 1 hr = 1/42 + 1/56 = 7/168 = 1/24 part. So they will do in 8 hrs = 8*1/24 = 1/3 part.
</h2><h2>
</h2><h2>Hence they need 1÷1/3 = 3 days to complete the work.</h2>
I don’t understand your answerso you can be more specific?
7x-1+7x+8+5x+2=180
7x+7x+5x+2-1+8=180
19x+9=180
19x=180-9
19x=171
19x\19=171\19
x=9
therefore,7x-1
7(9)-1
=62
therefore, 7x+8
7(9)+8
=71
therefore 5x+2
5(9) +2
=47
