16n = 320
Divide
16n/16 = 320/16
n = 320/16
n = 20
Answer: 20

Think of square roots of the same numbers as being like terms.
Think of
5x + 12y - 10x - 5y =
= 5x - 10x + 12y - 5y
= -5x + 7y
Think of sqrt(7) as x, and sqrt(6) as y.



Answer:
same

Answer:
∠ B = 54°
Step-by-step explanation:
Supplementary angles sum to 180°.
Sum A and B and equate to 180, that is
7x + 14 + 5x - 26 = 180, that is
12x - 12 = 180 ( add 12 to both sides )
12x = 192 ( divide both sides by 12 )
x = 16
Thus
∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°
