I believe you are trying to say 25% of a number is 9, what is the number? in that case the answer is 36. just divide 9 by .25
3a+7+2a and 7a+5. These expressions are not equivalent. 5a+7 does not equal 7a+5.
Since y+8 is positive, you don't have to find the absolute value since the absolute value is y+8. all you have to do is find a number that makes the statement true for y. the symbol between next to the 3 asks for a number that is greater or equal to 3. So your answer would be
≥-5
1.875 is what you are looking for.
