Answer:
12 and 1/4
Step-by-step explanation:
This is a fairly simply problem all you have to do is all all the fractions given. So we get the equation 4/8 + 5/8 + 5/8 + 1 1/8 + 1 1/8 + 1 4/8 + 1 4/8 + 1 4/8 + 1 6/8 + 2. This makes the equations easy since all the denominators are the same. First we must make all the fractions improper fractions. This will make the equation 4/8 + 5/8 + 5/8 + 9/8 + 9/8 + 12/8 +12/8 + 12/8 + 14/8 + 16/8. Then we can add all the values together and we get 98/8 which simplifies to 12 2/8 which further simplifies to 12 and 1/4.

Answer:
x > -3
Step-by-step explanation:
3(x + 2) > X.
⇒ 3x+6 > x
⇒3x+6-x > x - x [subtract x from both sides]
⇒2x + 6 > 0
⇒2x + 6 - 6 > -6 [subtract 6 from both sides]
⇒2x > -6
⇒x > -6/2 [Dividing both sides by 2 ]
∴ x > -3
