Since this is a proportion we cross multiply.
b+2/b-1=4/5
b-1(4)=b+2(5)
4b-4=5b+10
+4 = +4
4b=5b+14
-5b=-5b
-1b=14
divide by -1 on both sides
b=-14

Answer:
Korea = 15
Italy = 16
France = 17
Step-by-step explanation:
Let :
Korea = x
Italy = x + 1
France = x + 2
(since the values are consecutive)
x + x + 1 + x + 2 = 48
3x + 3 = 48
3x = 48 - 3
3x = 45
x = 45 / 3
x = 15
Korea = x = 15
Italy = x + 1 = 16
France = x + 2 = 17
Answer:
x=17
Step-by-step explanation:
Since the triangles are congruent, the angles are equal
I≅ P
3x+4 = 72-x
Add x to each side
3x+4+x = 72-x+x
4x+4 = 72
Subtract 4 from each side
4x+4-4 = 72-4
4x= 68
Divide by 4
4x/4 = 68/4
x = 17
