1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ <u>5x - 7y = -10</u>
<u>27y</u> = <u>65</u>
27 27
y = 2¹¹/₂₇
x + 4(2¹¹/₂₇) = 11
x + 8²²/₂₇ = 11
<u> - 8²²/₂₇ - 8²²/₂₇
</u> x = 2⁵/₂₇
(x, y) = (2⁵/₂₇, 2¹¹/₂₇)
Answer:
2. 10 muffins with chocolate 30 without chocolate
Step-by-step explanation:
<em>I </em><em>think </em><em>41 </em><em>is </em><em>correct </em><em>answer</em>
Step-by-step explanation:

Answer:
48
Step-by-step explanation:
821 rounded down to 800
17 rounded up to 20
820/20 =41
20x41=820
17 x 41 = 697
17 x 51 = 867
Midpoints
697+867/2 = 782
41 +51/2 = 46
46 x 17 = 782
47 x 17 = 799
48 x 17 =816
49 x 17 =833
50 x 17 =850
So, the highest number is 48.
The closest we can get is 48 x 17=816 & without going over 821.
