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

$-7+\frac{f}{2}+7=-1+7$

Then simplify by equation.

$\frac{f}{2}=6$

Next, you multiply by two from both sides of equation form.

$\frac{2f}{2}=6*2$

And finally, simplify by equation.

$6*2=12$

$2*6=12$

$12/6=2$

$12/2=6$

$f=12$

Final answer: $\boxed{f=12}$

Hope this helps!

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

MakcuM [25]

Answer:

3 / 91

Step-by-step explanation:

Given :

Red balls = 3

Blue balls = 4

Green balls = 4

Yellow balls = 3

Total number of balls = (3+4+4+3) = 14

Sample space :

RR, BB, GG, YY, RB, BR, BG, GB, YG, GY, YR, RY, BY, YB, GR, RG

Probability of drawing two red balls without replacement :

1st draw :

P(red) = number of red balls / total number of balls

P(red) = 3/14

2nd draw :

P(red) = 2 / 13

Hence,

P(RR) = 3/14 * 2/13 = 6 / 182 = 3 / 91

Mekhanik [1.2K]

Answer: Yes, it will be enough.

Step-by-step explanation:

I will answer this in English:

We have 27 students and 81 units, we want to give 3 units to each student.

This is only possible if the quotient betwen 81 and 3 must be bigger than 27.

Lets do it:

81/3 = 27

So we have exactly enough for the 27 students.
