Answer:

x = 3, y = 11

Step-by-step explanation:

Given

2x + 3xi + 2y = 28 + 9i

Compare coefficients of like terms on both sides.

Comparing i terms

3x = 9 ( divide both sides by 3 )

x = 3

Comparing constant terms

2x + 2y = 28 ← substitute x = 3

2(3) + 2y = 28

6 + 2y = 28 ( subtract 6 from both sides )

2y = 22 ( divide both sides by 2 )

y = 11

Answer:

A) Quincy should buy 22 rolls

B) 43 rolls

C) she needs to buy 19 rolls of ribbon.

Step-by-step explanation:

yards of ribbon = 322

ribbon comes in rolls= 15

Quincy should buy = 322/15 = 21.46

Quincy should buy 22 rolls

Twice the length of 322 yards is 644 yards. If I divide 644 by 15, the answer is 42 r 14. Because there is a remainder, we need to round the quotient up to 43.

Alice needs to buy 43 rolls of ribbon.

If we divide the total amount of ribbon, 285, by the amount of ribbon in each roll, 15, we get:

285 ÷ 15 = 19

So, she needs to buy 19 rolls of ribbon.

One possible combination could be:

10 rolls of yellow ribbon = 150 yards

5 rolls of red ribbon = 75 yards

4 rolls of blue ribbon = 60 yards

total of: 10+5+4=19 rolls

Since there are 15 yards of ribbon in each roll, the total amount of ribbon will be:

15×19=285

So answer is correct

Thanks!
