5x + 6y = 20 , 8x - 6y = -46

serg [7]

Answer:

5x + 6y = 20_____(1)

8x - 6y = -46_____(2)

Solving simultaneously:

Eqn(1) + Eqn(2)

5x + 8x + 6y + (-6y) = 20 + (-46)

13x = -26

x = -2

substituting this into Eqn (1):

5(-2) + 6y = 20

-10 + 6y = 20

6y = 30

y = 5

hence:

x = -2,y = 5.

After robbing a bank in dodge city, a robber gallops off at 14 mi/h. 20 minutes later, the marshall leaves to pursue the robber

Morgarella [4.7K]

For this case we have to write the equation of the position of each one.

We have then:

For the robber:

$r = 14t$

For the marshall :

$r = 16 (t- (\frac{20}{60}))$

$r = 16 (t-\frac{1}{3})$

By the time the marshall reaches the robber we have:

$14t = 16 (t-\frac{1}{3})$

From here, we clear the time.

We have then:

$16t - 14t = \frac{16}{3}$

$2t = \frac{16}{3}$

$t =\frac{8}{3}$

$t = 2.7 h$

Answer:

it takes the marshall to catch up to the robber about 2.7 hours.
