Answer:

12 3/8

Step-by-step explanation:

8-1/2+5-1/8

8+5  -1/2 - 1/8

Lets get a common denominator of 8

8+5 - 1/2 *4/4 - 1/8

8+5 - 4/8 - 1/8

Combine the whole numbers and the fractions

13 -5/8

Now we need to borrow from the whole number

12 + 1 - 5/8

12 + 8/8 -5/8

12 +3/8

12 3/8

Solve -3(x+5) = -9 solve
Bumek [7]
-3(x + 5) = -9
-3x + -15 = -9
-3x - 15 = -9
-3x - 15 + 15 = -9 + 15 (we added 15 to both sides of the equation because now, the 15 on the left side cancels out).
-3x = 6
-3x/-3 = 6/-3
X = -2
So, in conclusion, X is equal to -2.
