Answer:
n=0
Step-by-step explanation:
3n+4+14n=4-32n
3n+14n=-32n
17n=-32
17n+32n=0
49n=0
7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
Try a few:
1+3+5=9 too small
5+7+9= 21 just right
The greatest integer is 9
Answer: 176
Step-by-step explanation:
To evaluate the equation we have to remove the parentheses and add 15 + 17...
1/2 (11)(15 + 17) =
= 11 * 32 * 1/2
Now, we have to turn it into a fraction and multiply it...

= 
352 ÷ 2 = 176
I hope this helps!
