Phoenix [80]

Answer: 17/18

Step-by-step explanation: You have to find the least common denominator first, since 1/9 and 5/6 have different denominators. The least common denominator is 18. Multiply both the numerator and the denominator of each fraction by the number that makes its denominator equal to the least common denominator.

The equation then becomes 2/18 + 15/18 which equals 17/18 ^-^

Someone help... pleaseee
frutty [35]

Answer:

2x + 8

Step-by-step explanation:

Don't worry, this is simple! Add up the common terms.

For example, you can't add up 2x and 5, because 2 is being multiplied by a variable.

So combine the x terms: 2x

And the numerical terms: 8

Combine 2x and positive 8.

2x + 8
