1/2 + 1/3 = 3/6 + 2/6 = 5/6.....so 5/6 of the total marbles are red and white.
That means 1/6 are blue. So if 6 are blue, then 1/6 of the total marbles = 6
1/6x = 6
x = 6 * 6/1
x = 36.....there are 36 total marbles
1/2 are red.....so 1/2(36) = 36/2 = 18 are red
1/3 are white......1/3(36) = 36/3 = 12 are white
and 6 are blue.
Answer:
the third option (x,y) -> (-x, -y+5)
Step-by-step explanation:
222.118 estimated is 222.1 and 236.103 estimated is 236.1 so subtracted equals 14.0

Hey there! :)
Answer:
Choice C: x + 8 = 3x.
Step-by-step explanation:
Solve this question by simplifying each answer choice:
a) 4x = 20
Divide both sides by 4:
4x/4 = 20/4
x = 5. This is incorrect.
b) x/2 = 8
Multiply both sides by 2:
x = 16. This is incorrect.
c) x + 8 = 3x
Subtract x from both sides:
8 = 2x
Divide 2 from both sides:
x = 4. This is correct.
d) x = x+5 /2
Multiply both sides by 2:
2x = x + 5
Subtract x from both sides:
x = 5. This is incorrect.
Therefore, choice C is the correct answer.
