Question

Calcule a medida x indicada: a)x/5=14/10 b)3,4/x=12/18 c)0,9/0,5=x/3,5

Answer 1

a)$\dfrac{x}{5} =\dfrac{14}{10}$

$10x = 14*5$

$10x = 70$

$x = \dfrac{70}{10}$

$\boxed{x = 7}$

b) $\dfrac{3,4}{x} =\dfrac{12}{18}$

$12x = 18 * 3,4$

$12x = 61,2$

$x = \dfrac{61,2}{12}$

$\boxed{x = 5,1}$

c) $\dfrac{0,9}{0,5} =\dfrac{x}{3,5}$

$0,5x=0,9*3,5$

$0,5x=3,15$

$x=\dfrac{3,15}{0,5}$

$\boxed{x = 6,3}$
