Answer:

(-1, -2)

Step-by-step explanation:

multiply the top equation by 5

multiply the bottom equation by 3

15x - 25y = 35

15x - 6y = -3

subtract these two - x values cancel

-25 y = 35

6 y = 3

-19y = 38

y = -2

plug this back in to get x

15x + 12 = -3

15x = -15

x = -1

What fraction of 1km is 415m

Oksi-84 [34.3K]

<span><span>1. </span>Fraction of 1km is 415 m
In every 1 kilometers = 1 000 meters
=> 415 / 1 000 – this is already a fraction , we need to convert it into its simplest form
=> 415 / 1 000 = this will be divided by 5
=> 415 / 1 000 / 5/5 = 83 / 200
Thus, the fraction of 415 meter in 1 km is 83 / 200</span>
