ayudenme porfa lo nesesito para hoy

Answer 1

Explicación paso a paso:

1.

$16-\frac{T}{3} = \frac{-106}{7} \\\\\frac{T}{3}=\frac{218}{7}\\\\T = \frac{654}{7}=93,43$

2.

$x + 2/3 = 2x\\\\x = 2/3$

3.

$\frac{x}{4} + \frac{4}{3} = \frac{x}{3} \\\\\frac{x}{12} = \frac{4}{3} \\\\x = 16$

4.

Primer día = 90 km

Segundo día = (3/4)(90 km) = 67,5 km

Tercer día = (2/3)(67,5 km) = 45 km

5.

     a)

     Total = 160 km

     b)

     Carro = (3/4)(160) = 120 km

     Moto = (1/4)(120) = 30 km

     Bicicleta = (1/4)(30) = 7,5 km

     A pie = 160 - 120 - 30 - 7,5 = 2,5 km

6.

B = H + 3    ⇒    H = B - 3

Perímetro = 2B + 2H = 38

B + H = 17

B + B - 3 = 17

2B = 20

Base = 10 cm
