Answer:

BF = 18

Step-by-step explanation:

In triangle BCD, H is the Centroid.

Centroid of a triangle divides the median in the ratio 2 : 1.

Therefore, BH : HF = 2 : 1

Let BH = 2x & HF = x

Since, HF = 6.... (given)

So, x = 6

2x = 2*6 = 12

BH = 12

Now,

BF = BH + HF = 12 + 6

BF = 18

Answer:

The number of students attended was 334 and the number of non students attended was 127

Step-by-step explanation:

Let

x ----> the number students attended

y ----> the number of non students attended

we know that

$x+y=461$ ----> equation A

$3.50x+5.50y=1,867.50$ ----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

The solution is the point (334,127)

see the attached figure

therefore

The number of students attended was 334 and the number of non students attended was 127

Please help if you could. f/2 + 9 = 4 -9 -9 f/2 =

dmitriy555 [2]

Answer:

$\frac{f}{2} +9=4$

Subtract 9 from both sides:

$\frac{f}{2}+9-9=4-9$

$\frac{f}{2} =-5$

Multiply both sides by 2:

$2*\frac{f}{2} =-5*2$

$f=-10$

Which scenario best matches the linear relationship shown in the table ?

OleMash [197]

The answer is C. because on the chart it goes by 2 days not one so you'd need to divide. 76-48=28 (so she would spend 28 dollars per 2 days but its asking for ONE day so you'd divide that) 28/2=14

I tried to explain it as well as I could, hope this helped!
