- <em>Step-by-step explanation:</em>
<em>Hi ! </em>
<em>6x - 5y = 13</em>
<em>9y - 15 + 2x = 0</em>
<em />
<em>6x - 5y = 13</em>
<em>2x + 9y = 15 | ×(-3)</em>
<em />
<em>6x - 5y = 13</em>
<em>- 6x - 27y = - 45</em>
<em>add</em>
<em />
<em>6x - 6x - 5y - 27y = 13 - 45</em>
<em>- 32y = - 32 | ×(-)</em>
<em>32y = 32</em>
<em>y = 1</em>
<em>replace y = 1</em>
<em>6x - 5(1) = 13</em>
<em>6x - 5 = 13</em>
<em>6x = 13 + 5</em>
<em>6x = 18</em>
<em>x = 3</em>
<em>Good luck !</em>

<h3>Answer:</h3>
- x = 9
- x = 9
<h3>Explanation:</h3>
1. The two marked angles are supplementary, so their sum is 180°.
... (15 +5x) + (14x -6) = 180
... 19x + 9 = 180 . . . . . . collect terms
... 19x = 171 . . . . . . . . . . subtract 9
... x = 9 . . . . . . . . . . . . . divide by 19
2. The two marked angles are corresponding angles, so are congruent.
... 13x -7 = 11x +11
... 2x -7 = 11 . . . . . . . subtract 11x
... 2x = 18 . . . . . . . . add 7
... x = 9 . . . . . . . . . . divide by 2
Answer: N=0
Step-by-step explanation:
0=−5n−2n
Rewrite the equation as −5n−2n=0. -5n−2n=0 S<em>ubtract 2n from −5n</em>. −7n=0 Divide each term by −7 and simplify.
Samuel could round both of the individual numbers, to get s rounded answer. So, he could round 23 to 20, and 395 to 400, to get a product of 8000.
Or, he could multiply the numbers first, so 23*395 to get a product of 9085, which would then round to 9000, or depends on what place value it would want to be rounded to.
Answer:
study of the geometric properties of solutions to polynomial equations, including solutions in dimensions beyond three. (Solutions in two and three dimensions are first covered in plane and solid analytic geometry, respectively.)
