Answer:

(3, 2) is the ordered pair for the given system of equations.

Step-by-step explanation:

Given:

2 x+ y = 8.......................(i)

y = - x + 5........................(ii)

Put y = - x + 5 in equation (i)-

2 x + ( - x+ 5) = 8

2 x - x + 5 = 8

x = 8 - 5

x = 3

Now put x = 3 in equation (ii)-

y = - 3 + 5

y = 2

Hence the (3, 2) is the correct ordered pair.

Answer:

n-3

Step-by-step explanation:

for every input, the output is three less (4-3=1, 7-3=4, 8-3=5). That rule needs to stay consistent, so no matter what the input is (n), the output is always going to be three less than, making it y or output=n-3

You’re trying to find the better buy so you want to find out how much you’re paying per unit (in this case kg)

So you divide the price by the unit (kg)

And find the better buy by looking at which price is cheapest.

Your answer is the 7.48 kg bag

Hope this helps and good luck!!
