Step-by-step explanation:
The anwser to this problem is $2.71
8 Broken toys : 42 total toys = 1 Broken toy : 6 total toys
20 Broken toys : 105 total toys = 4 Broken toy = 21 total toys.
Answer: No: They are not proportional.
It would be 10.
Reason:
5x1= 5
5x2=10
5x5=25
5x20=100
B.) x=-5/2
4-(2x+4)=5
4-2x-4=5
-2x=5+4-4
-2x=5
x=5/-2
x=-2.5, or -5/2
