Answer:

y = -11

Step-by-step explanation:

y - 3 (2y - 7) = 76

distribute the three to the two values in the parenthesis!

y - 6y + 21 = 76

now combine like terms, baiscally add y to -6y

-5y + 21 = 76

now subtract 21 from both sides

-5y = 55

then divide by negative 5

y = -11

Does anyone know how to answer this question? Please write your working calculation as well if you do know the answer. Thanks so

Answer:

Mark as brainliest if helped Thanks!

Step-by-step explanation:

funtion is:

$y = \frac{x^2 -1}{2x + 1}$

therefore $\\\frac{dy}{dx}\\$ is

$\frac{d\frac{x^2 -1}{2x + 1}}{dx}$

$\frac{\frac{x^2 -1}{2x + 1}}{x}$

$\frac{x^2 -1}{(2x+1) x}$

Now

$\int\limits^2_0 {\frac{x^2 +x +1 }{4x^2 +4 + 1} } \, dx$

(Calculation of this it too long and it is hard to type on brainly)

here is the answer though....

= 4/5

=0.8

a store is selling 6 bags of marbles for $18 what is the unit price for bags of marbles use double number line diagram to suppor

Alenkinab [10]

Answer:

We know that the prize of 6 bags of marbles is $18.

Then if each one of the bags costs C, the 6 bags will cost a total of 6 times C.

Then the cost is:

6*C

and this is equal to $18

6*C = $18

Now we want to solve this for C, remember that we can divide both sides of the equation by the same number, then let's divide both sides by 6:

6*C/6 = $18/6

C = $18/6 = $3

Each bag costs $3.

Below you can see a double number line, where above is the number of bags and below is the prize:
