Step-by-step explanation:
6x+x=34+1
7x=35
x=35/7
x=5
Hence this equation has only one solution
Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
All of these are mostly approximately
1) 250.3
2)3421.19
3)11494.04
4) 3.108
8/15 or somthing like that it you might be souposed to solve it diferent than i did
