For which equation is  not a solution? x=-1/3

Mathematics
1 answer:
aniked [119]4 years ago
3 0
The answer is B. 
We can prove this by putting -1/3 into x. 
6(-1/3) - 5 = 7 
Multiply -1/3 by 6. 
-2 - 5 = 7 
Subtract 5 from -2. 
-7 \neq 7 
So, -1/3 is not a solution to this equation. 
Hope this helps!

vovangra [49]

Based on the figures above, the numbers of children that attended the park that day is 10,000.

<h3>What is the matrix equation about?</h3>

Fist we have to use the determinant to solve for c and as such:

\frac{det.\frac{30000}{500000}    \frac{1}{20} }{det. \frac{1}{10}  \frac{1}{20}  }

=\frac{30000 x 20 - 500000 x 1}{1 x 20 - 1 x 10}

= 100000/10

=10,000

Therefore, Based on the figures above, the numbers of children that attended the park that day is 10,000.
