Answer:
Option C is correct.........
275 + 180 + 120
275 + 300 -- 180+120
575 --- 275+300
there you go
[1] 7x + 6y = -10
[2] -2x + y = 11 --> y = 11 + 2x
Replacing [2] in [1]
7x + 6(11 + 2x) = -10
7x + 66 + 12x = -10
7x +12x = -10 -66
19x = -76
x = -76/19
x = -4
Replace x=-4 in [1]
7(-4) + 6y = -10
-28 + 6y = -10
6y = -10 +28
6y = 18
y = 18/6
y = 3
Checking solutions in [2] x=-4, y=3
-2x + y = 11
-2(-4) + 3 = 11
8 + 3 = 11
11 = 11
Answer:

Step-by-step explanation:
We can rewrite the compound fractions to get 5/4 * 11/5
Multiply these to 55/20
Now let's look at the other side
5/6 * 11/5 = 55/30
Since the numerators are the same but the denominators are different, the fraction with the lower denominator is greater
55/20 > 55/30
Hope this helps
