C = 2πr
141.3 = 2(3.14)r
141.3 = 6.28r
22.5 = r
Answer:
x = -1/7 or -0.14285 - in decimal form
Step-by-step explanation:
8x + 5 = -6x + 3
8x + 6x = 3 - 5 { change side }
14x = -2 { basic addition and subtraction }
x = -2/14 { changing sides }
x = -1/7 { simplified }
54 - 18n
Multiply -9 by -6 to get 54.
Multiply -9 by 2n to get 18n.
