Answer:
B) 1
Step-by-step explanation:
x+1/2(x-4)=1/2x+6(x-2)
x+1/2x-4/2=1/2x+6x-12
x+1/2x-1/2x-2=6x-12
x-2=6x-12
x-6x-2=-12
-5x-2=-12
-5x=-12+2
-5x=-10
5x=10
x=10/5
x=2
the required value of c is [ -11 -1
2 5]
≈ 4.89
A = πr²
75 = 3.14 x r²
r² = 75 / 3.14 = 23.89
r = 4.89
2 2/5 or 12/5
Hope this helps :)
