<u>Question 10:</u>
21.75 ÷ 30 = 0.725
Move the decimal backwards 2 times
72.5
<em>Answer: </em>72.5%
<u>Question 11:</u>
Sales: $768
Commission Rate: 4%
Commission: $30.72
768 x 4 = 3,072
3,072 ÷ 100 = 30.72
<em>Answer:</em> $30.72
<u>Question 12:</u>
Selling Price: $39.98
Tax Rate: 4.5%
Sales Tax: $1.80
39.98 x 4.5 = 179.91
179.91 ÷ 100 = 1.7991
Then you round to the thousandths.
1.799
1.8
<em>Answer:</em> $1.80
<u>Question 13:</u>
20% x 141 = 28.2

Not sure why it needs to be a fraction, if I am missing something please tell me. 64 or 64/1
<span>5x²y + 2xy² + x²y
Combining like terms would be
6x²y + 2xy²
The two terms are now unique and cannot be combined any further. </span><span>

2x + y = 1
2x - 2x + y = 1 - 2x
y = 1 - 2x
y = -2x + 1
4x + 2y = -1
4x + 2(-2x + 1) = -1
4x + 2(-2x) + 2(1) = -1
4x - 4x + 2 = -1
2 ≠ -1
The solution of the problem can't be a solution because they are both parallel lines, which means they have no solution.
