Answer:
k = 4
Step-by-step explanation:
Step 1: Write equation
-3k - 9 = -21
Step 2: Solve for <em>k</em>
- Add 9 to both sides: -3k = -12
- Divide both sides by -3: k = 4
Step 3: Check
<em>Plug in k to verify it's a solution.</em>
-3(4) - 9 = -21
-12 - 9 = -21
-21 = -21
if u calculate 3 1/4 u would get 13/4
This means to get the reciprocal fraction of 13/4 just turn it upside down like this
13/4= 4/13 so ur answer is 4/13
You can use mathpapa for 1,2,3 and 4 :)
