11
Step-by-step explanation:The radius will always be half of the diameter therefore it will be 11
44.4
yes
a) 5x=8 use a calculator and use distributive property
b) 22=3x+5 -18
22=3x-13
9=3x
x=3
distributive property
c)-48= -8x-20+5x-1
-48= -3x-21
-27= -3x
x=7
3 : 8
cross multiply
8x = 3y
x = 3/8
x : y = 3 : 8
21 divided by 7 is 3 so each candy bar equals 3 dollars
