Question

calcule o valor de x,y,w, é z

Answer 1

X + W + Y + Z  = 220

( x + w + y + z )/ (25 + 30 +40 + 15) = x/25 = w/30 = y/40 = z/15
220/110  = x/25 = w/30 = y/40 = z/15
2/1 = x/25 = w/30 =y/40 = z/15

x/25 = 2/1
x = 25 * 2 = 50 ***

w/30 = 2/1
w = 2 * 30 = 60 ***

y/40 = 2/1
y = 2 * 40 = 80 ****

z/15 = 2/1
z = 2 * 15 = 30 ***
