Answer:
x+y+z=180
Since y+z=5x, x+5x=180, so x=30
So,
30+y+z=180
y+z=150
Since z=y+24, y+y+24=150
2y=126
y=63
30+63+z=180
z=87
So x=30, y=63, z=87

Step-by-step explanation:
-4x + 35 > 2
Subtract 35 from both sides:
-4x> -33
Divide both sides by -4:
X > -33 s -4
Because you are dividing the inequality. Y a negative value, reverse the inequality sign.
X < 33/4

Answer: 7/12</h3>
=================================================
Explanation:
There are B = 3+5+4 = 12 marbles total, of which A = 12-5 = 7 are not black. Or you could note that we have A = 3 red + 4 white = 7 marbles that are not black.
The probability of selecting a non-black marble is A/B = 7/12
7/12 = 0.5833 = 58.33% approximately
