Answer:

(-1.5, -2)

Step-by-step explanation:

multiply the first equation by -8

-4x - 4 + 4y - 2 = -8

-4x + 4y = -2

multiply the second equation by 6

3y + y - 1 = 6x

6x - 4y = -1

Now add the 2 equations together

2x = -3

x = -1.5

plug that back in to solve for y

-4(-1.5) + 4y = -2

4y = -8

y = -2

A bag has 5 red marbles, 4 blue marbles, 8 green marbles, and 3 yellow

kozerog [31]

Answer:

40% of the total marbles are green.

Step-by-step explanation:

Percentage: Green marbles/Total marbles

=> 8/5 + 4 + 8 + 3
=> 8/20

Percentage formula: $\frac{a}{b} (100)$

=> 8/20 x 100
=> 8 x 5
=> 40

Hence, 40% of the total marbles are green.
