Answer:
y = -1 , x = 4
Step-by-step explanation:
(4x - 5y = 11) x8
(8x - 5y = 27) x4
32x - 40y = 88
- - -
32x - 20y = 108
[0. 20y = -20] divide both by 20
y = -1
8x - 5y = 27
8x - 5(-1) = 27
8x = 27 + 5
8x = 32 ( divide both by 8)
x = 4
Answer:
-2
Step-by-step explanation:
m=
<span>The glass is not always half full
</span><span>Conditional i think</span>
Other number: x
one number: 5x - 2
x (5x - 2)=72
5x^2 - 2x = 72
I find it easier to put them in decimal form then to try and find a common denominator
2/3 = 0.666
2/9 = 0.222
5/6 = 0.833
11/18 = 0.611
least to greatest = 2/9, 11/18, 2/3, 5/6
