Answer:5

Step-by-step explanation:

Simplifying

8x + -20 = 3x + 5

Reorder the terms:

-20 + 8x = 3x + 5

Reorder the terms:

-20 + 8x = 5 + 3x

Solving

-20 + 8x = 5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-20 + 8x + -3x = 5 + 3x + -3x

Combine like terms: 8x + -3x = 5x

-20 + 5x = 5 + 3x + -3x

Combine like terms: 3x + -3x = 0

-20 + 5x = 5 + 0

-20 + 5x = 5

Add '20' to each side of the equation.

-20 + 20 + 5x = 5 + 20

Combine like terms: -20 + 20 = 0

0 + 5x = 5 + 20

5x = 5 + 20

Combine like terms: 5 + 20 = 25

5x = 25

Divide each side by '5'.

x = 5

Simplifying

x = 5

A chemist is using 336 milliliters of a solution of acid and water. If 19.4 % of the solution is acid, how many milliliters of a
denpristay [2]

Answer:

65.2 milliliters

Step-by-step explanation:

The quantity 336 milliliters is the 100% of the solution. We can represent this information on a table:

Milliliters        Percentage of solution

     336        ⇔            100%

we are told that 19.4% of this solution is acid, and we need to know how many milliliters represents this percentage. I will call the number of milliliters of acid on the solution 'x', and updating the last table:

Milliliters        Percentage of solution

     336        ⇔            100

     x             ⇔            19.4%

We can solve this problem for 'x' using the<u> rule of three</u> which is to multiply the cross quantities on the table (336 by 19.4) and then divide by the remaining amount (100):

x = 336(19.4)/100

x = 6,518.4/100

x = 65.184

which rounding to the nearest tenth is: 65.2 milliliters
