What is the value of f? 6f−12=−4f+6

Xelga [282]

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.

Dana has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the ra

Sedaia [141]

Answer:

2hrs 40 minutes

Step-by-step explanation:

The formula for distance is expressed as:

$d=st, s=speed, t=time$

#The time taken to run:

$d=st\\\\t=d/s\\\\t_r=d/8$

#The time taken to walk:

$d=st\\\\t=d/s\\\\t_w=d/2$

#Since the distances are the same:

$d_r=8t_r,d_w=2t_w\\\\8t_r=2t_w\\\\t_r+t_w=4->t_w=4-t_r\\\\\therefore8t_r=2(4-t_r)\\\\8t_r=8-2t_r\\\\t_r=1\frac{1}{3} \hrs\\\\t_w=4-1\frac{1}{3}=2\frac{2}{3}\ hrs$

Hence, Dana spends 2hrs 40 minutes walking back
