$\frac{3}{15}$ -<u /> $\frac{d}{5}$ -( $\frac{5}{6}$ + $\frac{d}{3}$ =0

Step 1:<u /> $\frac{5}{6}$ + $\frac{d}{3}$ =<u /><u /> $\frac{3}{15}- \frac{d}{5}- \frac{(2d+5)}{6}=0$

Step 2: $\frac{1}{5}- \frac{d}{5}= \frac{(1-d)}{5}- \frac{(2d+5)}{6}=0$

Step 3: $\frac{(1-d)*6-(2d+5)*5}{30}= \frac{-1*(16d+19)}{30}$

Step 4: $16d= -19:Divide \ both \ sides \ by \ 16:d= \frac{-19}{16}= -1.188$

Your answer is <u /> $d\boxed{\boxed={ \frac{-19}{16}= -1.1888}}}}$

3/15 -(d/5)=5/6+(d/3)
-(d/5)-(d/3)=5/6-3/15

-(8d/15)=19/30
-8d=19/2
-d=76
d=-76

enot [183]

You can do
83 - 5 to find the answer
So that's

"During the tryouts for a university pep band, there were 4 trumpet players, 12 drummers, and 7 saxophonists. How many ways can

sladkih [1.3K]

The ways can the jazz band be selected so there are 2 trumpet players, 5 drummers, and 3 saxophonists is given below .

Step-by-step explanation:

Let's first do the math with only the trumpet,drummer and saxophonists player.

There are 4 Trumpet Player. There are 4 choices of trumpet players. Which means for each drummer, there are 4 groups of musicians:

T 1 D1S1

T 1 D2S2

and so on

So if there are 4 groups of musicians for each Trumpet ,12 drummer and there are 7 saxophonists , we get 12 groups.

It would be the product of

4T2, 12D5 and 7S3

That is 6*792*35=166,320

(6,-3) and y = - 6x - 3

Hatshy [7]

Wait what's the question tho?
is it if this point is on the line?
cause it's not
-y=mx+b
3=-6(6)-3
-3=-36-3
-3 does not equal -39
hence, point is not on the line

Peter mixes 4 1/2 cups of orange juice, 2 1/4 of ginger ale and 6 1/3 cups of strawberry lemonade to make some punch. What is th

ruslelena [56]

To add these amounts together, we must first find their least common multiple in order to get common denominators (b/c when you add fractions, the denominators must be the same).

We'll start by listing some of their multiples.
To do this, count by whatever the denominator is:
4 1/2 (denominator is 2): 2 4 6 8 10 12 14
2 1/4 (denominator is 4): 4 8 12 16
6 1/3 (denominator is 3): 3 6 9 12 15

Look and see which is the first multiple that all three denominators have. Circle them if it helps you. In this case, it's 12.

So now we have to multiply the denominators by whatever number it takes to reach 12, and multiply by the same number to the numerator:

4 1/2 (times 6 to both top and bottom) =
4 6/12

2 1/4 (times 3) = 2 3/12

6 1/3 (times 4) = 6 4/12

Add all these fractions together, and you get 12 13/12, which is equal to 13 1/12.

Thus, Peter makes a total of 13 1/2 cups.

Hope this made sense! tell me if anything is confusing/incorrect :))

Find the domain of the graphed function.

Darya [45]

The domain of the graphed function is [-3, 2)

<h3>How to determine the domain and the range?</h3>

From the given graph, we have the following highlights:

Minimum x value = -3 (closed circle)
Maximum x value = 2 (open circle)

Open circles are represented with () while closed circles are represented with []

Hence, the domain of the graphed function is [-3, 2)
