Question

A/10 = 50/100
(x+2)/4 = 42/14
3f/10 = 15/2
18/(8+b) = 2/b




ajuda pvf

Answer 1

A/10 = 50/100

A/10 = 5/10

A = 5

(x+2)/4 =42/14

(x+2)/4 = 3

(x+2) = 12

x = 12 - 2

x = 10

3f/10 = 15/2

3f = 150/2

3f = 75

f = 75/3

f = 25

18/(8+b) = 2/b

(8+b)/b = 18/2

(8+b) = 9b

9b - b = 8

8b = 8

b = 8/8

b = 1
