Answer:
Using division equality property to solve for b. b=27
Step-by-step explanation:
A book cost $3
Mr. Grayson spent $81 on books
Let number of books be b
Total cost invest on book = 3b
This would be equal to $81
Therefore, 3b=81
Now we solve for b
Using division method of equality
If we divide both side by same number in equality.After division we get both are equal .
3b=81
Here we divide by 3 both sides
3b÷3=81÷3
b=27
Thus, Using division equality property to solve for b. b=27
Answer:
The final answers are n = 0 or n = -1/4.
Step-by-step explanation:
Given the equation is -5n(4n + 1) = 0.
The Zero-Product property says "if x*y=0, then x=0 or n=0 or both."
we have -5n(4n + 1) = 0.
We know -5 is not equal to 0.
It means n = 0 or 4n+1 = 0.
n = 0 or 4n = -1.
n = 0 or n = -1/4
So, final answers are n = 0 or n = -1/4.
