If these are diving fractions with these then it is 3 1/2 if they are not fractions then it is 0.22
I hope i helped!
X + 100 = 4x +49
x= 17
158+148+32+x = 360
338+x= 360
x= 22
Part a: 6:3 > 2:1
part b: 9:3> 3:1
The circumference of a circle with radius

is

. If the length of the radius is tripled, then the circumference becomes

, which is just 3 times the original circle's circumference.
