Step-by-step explanation:
Divide 5 on both sides, to get x=4
7 <span> more than 3 times a number </span>
<span>more than is code for + </span>
<span>times is multiply </span>
<span>so 7+3n=31 </span>
<span>solve: </span>
<span>3n=24 </span>
<span>n= 8</span>

Answer: <em>50°</em>
Step-by-step explanation:
<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>
<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>
<em>Now every triangle must add up to 180°</em>
<em>so lets take the angles we have now</em>
<em>90° +40°=130°</em>
<em>now take that 130°</em>
<em>180°-130°=</em><em>50°</em>
<em>Now check your work</em>
90°+40°+50°=180°
Angle 3 is 50°
