Answer
Find out the The numerical value of A - B and the numerical value of B - A .
To prove
As given
The expression 113.47 - (43.72 - 26.9) represents A.
The expression 113.47 - (26.9 - 43.72) represents B .
Thus
A - B = 113.47 - (43.72 - 26.9) - ( 113.47 - (26.9 - 43.72))
First solving the bracket terms.
A - B = 113.47 - (43.72 - 26.9) - 113.47 + (26.9 - 43.72)
= 113.47 - 16.82 - 113.47 - 16.82
= 113.47 - 113.47 - 16.82 - 16.82
= -33.64
Therefore the value of A- B is -33.64 .
Thus
B - A = 113.47 - (26.9 - 43.72) - (113.47 - (43.72 - 26.9))
First solving the bracket terms.
B - A = 113.47 - (26.9 - 43.72) - 113.47 + (43.72 - 26.9)
= 113.47 + 16.82 - 113.47 + 16.82
= 33.64
Therefore the value of the A - B is -33.64 and B - A is 33.64 .
On solving the linear equation, There are in total 24 unshaded squares and 16 shaded squares.
<h3>What is a linear equation?</h3>
Ax+By=C is the usual form for two-variable linear equations. A typical form linear equation is, for instance, 2x+3y=5. When an equation is provided in this format, finding both intercepts is rather simple (x and y).
squares, where x= number of squares
2x = shaded squares
Number of unshaded squares = 3x.
This is due to the fact that there are 3 times as many unshaded squares as there are shaded squares (2 times more unshaded = 3*). (shaded)
Overall, there are 40 squares (5 * 8), therefore 40 total squares—shaded and unshaded—are present.
2x+3x = 40
5x = 40
x = 40/5
x = 8
There are 3×8 = 24 unshaded squares
8×2 = 16 shaded squares in all.
Therefore, you may shade in 8 squares whatever you choose.
