What is the value of f? 6f−12=−4f+6

Mathematics

Xelga [282]3 years ago

First you had to add by twelve from both sides of equation form.

6f-12+12=-4f+6+12

Then simplify.

6f=-4f+18

Next, add by four-f from both sides of equation form.

6f+4f=-4f+18+4f

Simplify.

10f=18

Then you divide by ten from both sides of equation form.

\frac{10f}{10}= \frac{18}{10}

Finally simplify by equation.

f=\frac{9}{5}

Final answer: \boxed{f=9/5}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

The Royal Fruit Company produces two types of fruit drinks. The first type is 55% pure fruit juice, and the second type is 80% p
seropon [69]

We need 56 pints of the 55 % <em>pure fruit</em> juice and 84 pints of the 80 % <em>pure fruit</em> juice to prepare 140 pints of 70 % <em>pure fruit</em> juice.

<h3>How to use weighted averages to find the correct juice concentration</h3>

In this problem we have to use two kinds of juice with different concentrations. To get a certain concentration, we must adjust quantities of each kind and <em>weighted</em> averages offers a method that is easy to apply:

70 · 140 = 55 · x + 80 · (140 - x)

70 · 140 = 80 · 140 - 25 · x

25 · x = 10 · 140

x = 56

We need 56 pints of the 55 % <em>pure fruit</em> juice and 84 pints of the 80 % <em>pure fruit</em> juice to prepare 140 pints of 70 % <em>pure fruit</em> juice.

Please help! try to make it short if you can! thank you so much!
Mumz [18]

For a, x is equal to the sum of the measures of the inside angle because the total degrees of a triangle is 180 and the total degrees of a line is 180. Since both the line and the triangle are missing the same amount, x would equal the interior degrees that are listed. I don’t know what m<x means for b, but if it’s asking for the value of x it’s 62+78= 140° which makes the missing interior angle 40°. Hope this helps!
