Answer 1

Resposta:

saci = x

$\sf x+ x +x = 60\\3x= 60\\\\x = \dfrac{60}{3} \\\\x = 20$

curupira = y

$\sf x + y + y = 40\\20 + 2y = 40\\2y = 40 - 20\\2y = 20 \\\\y = \dfrac{20}{2} \\\\y = 10$

sapato = z

$\sf z+z+z = 21\\3z = 21\\\\z = \dfrac{21}{3} \\\\z = 7$

Calculo:

$\sf z + y. x = \\7 +(10 \times 20) =\\7 + 200 =\framebox {207}$
