grin007 [14]

Answer:

Step-by-step explanation:

First, turn the word problem into an equation:

n(a number) was divided by 2

\frac{n}{2}

followed by this quotient beying multiplied by 4

\frac{n}{2}*4

the product was added to 9

\frac{n}{2}*4+9

the total sum was 25

\frac{n}{2}*4+9 = 25

use PEMDAS to solve the equation

subtract 9 on both sides

\frac{n}{2}*4 = 16

cancel the 2 and the 4 using factorization

n*2 = 16

divide 2 on both sides

n = 8

You and your friend are making 30 liters of sodium water. You have liters of 10% sodium and your friend has liters of 22% sodium
iren [92.7K]
X liters of 10% + (30 - x) liters of 22% = 30 liters of 15% 

<span>Plugging in the numbers </span>
<span>x(10) + (30 - x)22 = 30(15) </span>

<span>Distribute </span>
<span>10x + 660 - 22x = 450 </span>

<span>Combine like terms </span>
<span>-12x = -210 </span>

<span>Divide both sides by -12 </span>
<span>x = 17.5 </span>
<span>30 - x = 12.5 </span>

<span>17.5 liters of 10% + 12.5 liters of 22% = 30 liters of 15%

THE TRICK IS TO JUST USE ONLY ONE VARIABLE</span>
