Answer:
Step-by-step explanation:
1). (10x - 27)° = (2x + 29)°
10x - 27 = 2x + 29
8x = 56
x = 7
<em>m∠W</em> = (2(7) + 29)° <em>= 43°</em>
2). (14x + 4)° + 51° + 55° = 180°
14x + 110 = 180
<em>x = 14</em>
In order to answer the question, you need to know the area of a circle.
Area = pi * r^2
Area = 3.14 * (100/2) ^ 2
Area = 3.14 * 50^2
Area = 7850 mils^2 = 0.00785 in^2
Answer:
$25
Step-by-step explanation:
Multiply $20 by 0.25 (which is 25% as a decimal)

Answer:
−15
Step-by-step explanation:
9−6+5−3+6−2+8(4−7)
=3+5−3+6−2+8(4−7)
=3+2+6−2+8(4−7)
=3+2+4+8(4−7)
=3+6+8(4−7)
=9+8(4−7)
=9+(8)(−3)
=9+−24
=−15
