Answer: 18
Step-by-step explanation:
The procedure is this:
72% of 25,
72/100 * 25,
0.72 * 25,
= 18
5
1/4n + 3
Plug 8 in for n so 1/4(8) + 3
1/4 x 8 = 2
2 + 3 = 5
6x + 8 = 50
Our goal is to get the variable x on its own.
We can start by subtracting 8 from each side. (subtraction prop. of eq. lets us do this)
6x + 8 - 8 = 50 - 8
6x = 42
Now, we must divide each side by 6 to find the value of x.
6x ÷ 6 = 42 ÷ 6
x = 7
18 / 44 = 9 / 22
There are 44 nuts in the bag, and 18 of them are peanuts. If you simplify the fraction, you get 9/22 chance of getting a peanut.
