4.000 plus 200 plus 90 plus 3
The answer is (3,-5). Hope this helps
-3(k+7)-5k+4=23
-3k-21-5k+4=23
Get rid of the numbers that aren't being multiplied by k:
-3k-5k=23+21-4
Add like things:
-8k=40
Divide by -8 on both sides to get k by itself and to make the equation even:
k=-5
Since this number ends with a .59, this means that we should round 156.59 to 157.00. But because we never use .00 unless we are dealing with money, it's just better to say 157 instead of 157.00.
Hope this helps!
