I think first one is 5x+6 <=11 not 5x+6>=11
and second one is 6w+6>18
Hello,
let x the first angle
5x the second
2/3 x the third
x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18
27+135+18=180
They are both correct it's just that the say it differently 8/4 IS 2 so yea. I'm a middle schooler.
<span>I can solve for x and y
A) 2x - 4y = 12
A) 2x = 4y + 12
A) x = 2y + 6
Substituting into B
B) 3* (2y +6) - 5y = 20
B) 6y + 18 -5y = 20
B) y = 2
B) x = 10

75 divided by 15 equals 5 so each mouse cost $5.
