Answer:

(x, y) = (2, -1.5)

Step-by-step explanation:

x + 2y = -1

5x - 4y = 16

<=>

(2)x + (2)2y = (2)(-1)

5x - 4y = 16

<=>

2x + 4y = -2

5x - 4y = 16

<=>

7x = 14

<=>

x = 2

(*)x + 2y = -1

=> 2 + 2y = -1

=> 2y = -3

=> y = -1.5

=> (x, y) = (2, -1.5)

Marci bought 4 yards of ribbon for $6 how much should marci expect to pay for 10 yards of the ribbon?
Vinvika [58]
Ok, let's find how much does 1 yard of ribbon cost. Let's divide!

6 / 4 = 1.5

Each yard costs $1.50, so let's multiply that by 101.5 * 10 = 15

Marci will pay $15 for 10 yards of the ribbon.
