__ 12 Half a number plus 3 is 8 Twice that number plus another number is 25 Which of the following equations represents the systems A (1)/(2)x+3=8 2(10)+y=25 (1)/(2)x+3=8 2x+y=25 B. (1)/(2)x+3=8 x+2y=25 D. (1)/(2)x+3=8 2x+2y=25

The correct answer is B.<br /><br />The given information can be represented as a system of equations:<br /><br />$\frac{1}{2}x + 3 = 8$<br />$2x + y = 25$<br /><br />This system of equations can be represented as:<br /><br />$\frac{1}{2}x + 3 = 8$<br />$2x + y = 25$<br /><br />Therefore, the correct answer is B.
