Answer:
14
Step-by-step explanation:
Think how many times does 6 go into 84.
you can divide 84 into 6 which is 14.
Or you can think what times 6 equals 84.
-1/4 + f/8 = 1/2.
The LCD is 8. Rewrite this equation as -8/4 + 8f/8 = 8(1/2) and then reduce the result:
-2 + f = =4
Then f = 6.
You should check this result.
Not too sure what you're asking, but...
3(x+2) is the expression
6x + 9 < 63
Subtract 9 from both sides.
6x < 54
Divide 6 by both sides.
x < 9
