Answer:
3rd option: x= 40
Step-by-step explanation:
4x° +20°= 180° (adj. ∠s on a str. line)
<em>Bringing</em><em> </em><em>constants</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>:</em>
4x°= 180° -20°
<em>Simplify</em><em>:</em>
4x°= 160°
<em>Divide</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
x°= 40°
Thus, x=40.
Answer:
w = -3
Step-by-step explanation:
-4w - 4 = 8
Combine the constants by adding 4 to both sides.
-4w = 12
Isolate w by dividing by -4.
w = -3
Check your work by plugging w = -3 into the original equation.
-4(-3) - 4 = 8
12 - 4 = 8
8 = 8
Your answer is correct.
Answer:
translation then reflection
Step-by-step explanation:
Answer:
x = -3
Step-by-step explanation:
Take the 3x away from the right side.
-5x-3x=-8x
-8x = -24
Divide both sides by 8.
-8x/8 = x
-24/8 = -3
x = -3
