Answer:
r ≤ -1
Step-by-step explanation:
Given in the question
<h3>
3r+2(12r+7) ≤ 5r-8</h3><h3>
It can be solve by Simplifying and Reordering the terms</h3>
3r + 2(12r) + 2(7) ≤ 5r - 8
3r + 24r + 14 ≤ 5r - 8
27r + 14 ≤ 5r - 8
27r - 5r +14 + 8 ≤ 0
22r + 22 ≤ 0
22r ≤ -22
Move term containing r to the left, all term to the right.
r ≤ -22/22
simplifying
r ≤ -1
all negative integers which are smaller than or equal to -1
<u><em>To</em><em> </em><em>find</em><em> </em><em>:</em><em> </em></u>
<em><u>Solution</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em>
- 2x + 41 + 127 = 180 ( Angle Sum Property )
- 2x + 168 = 180
- 2x = 180 - 168
- 2x = 12
<em>Now</em><em> </em><em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>,</em><em> </em>
<em>So</em><em> </em><em>,</em><em> </em><em>we</em><em> </em><em>got</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em>
- <em>Answer</em><em> </em><em>:</em><em> </em>6
