this is a link to a video about subtracting decimals simply
7.09 Because it goes tens, hundredths, thousandths. Since our problem is nine hundredths the answer will have two numbers. 7 is the whole number so it goes before the decimal. :)
Distribute and combine like terms:
-12.6k -12 +7k +5
Simplified equation: -5.6k -7
If you are solving for k:
-5.6k - 7 = 0
-5.6k = 7
k = -7/5.6
Combine like terms
2n^6 - 24n^5 + 64n^5
2n^6 + 40n^5
factor out 2n^5
2n^5 (n + 20)
answer: 2n^5 (n + 20)
-6(y+15)= -3y+6
-6y-90 = -3y+6
-6 -6
-6y-96 = -3y
+6y +6y
-96 = 3y
/3 = /3
y= -32
