Answer:
x=25
Step-by-step explanation:
3x-5=2x+20=4x-30
3(25)-5 = 2(25) + 20 = 4(25) - 30
75-5 = 50 + 20 = 100 - 30
70=70=70

Interesting think. So sorry if you get it wrong
We have to calculate the perimeter of the figure to the nearest tenth of a millimeter. This figure is made of a rectangle and a half of a circle. The first figure has the perimeter: 3 + 6 + 3 = 12 mm. The second figure has the perimeter: 2 * Pi * r / 2 = Pi * r ; and the radius : r = 6/2 = 3 mm. So Pi * 3 = 3.14 * 3 = 9.42. Fimally : 12 + 9.42 = 21.42 or 21.4 to the nearest tenth. Answer: C. 21.4 millimeters<span>. </span>
