Answer:
C f=9
Step-by-step explanation:
isolate f on one side so you subtract 5 from both sides to get 3f=27 and then divide by 3 on each side to get f=9
The answer is b:
First change the operation to multiplication, and then change the last fraction to it's reciprocal (7/15 / 5/3)
Then, you can simplify 15 and 5 to 3 and 1 (divide each by 3)
Finally u multiply (7*1 / 3*3)
Sorry if its bad first time
| -2.3 | = 2.3
the absolute value of any number is positive, even if it says negative
4(3 + 3) = 4(3) + 4(3).....this is the distributive property
