-33 is a rational number. It is an integer with a definitive stopping point (by this I mean it is not a decimal number with endless repeating digits).

Combine as indicated by the signs. 8-y/3y + y+2/9y - 2/6y

Taya2010 [7]

Answer:

26 + y

----------

Step-by-step explanation:

Your using parentheses here would remove a great deal of ambiguity. Looking at your 8-y/3y + y+2/9y - 2/6y, I have interpreted it to mean:

(8-y)/3y + (y+2)/9y - (2/6)y. For example, without parentheses, your 8-y/3y might be interpreted differently, as 8 - y/(3y), or 8 - 1/3.

Looking at (8-y)/3y + (y+2)/9y - (2/6)y again, we see three different denominators: 3y, 9y and 6 y. The LCD here is 9y. Multiplying all three terms of (8-y)/3y + (y+2)/9y - (2/6)y by the LCD, we get:

3(8-y) + (y+2) + 3y. We must now divide this by the LCD:

3(8-y) + (y+2) + 3y

--------------------------

Next we need to perform the indicated multiplication:

24 - 3y + y + 2 + 3y

----------------------------

and then to combine like terms:

24 + 2 - 3y + y + 3y, 26 + y

---------------------------- or -----------

f(x)=-3x+12 represents the amount of ounces of juice left in a bottle after you take x gulps. How many gulps did you take if the

notka56 [123]

Answer:

3 gulps

Step-by-step explanation:

In this problem, f(x) = 3. Plug this into the equation:

3 = -3x + 12

Solve for x:

3 - 12 = -3x + 12 - 12

-9 = -3x

-9 / -3 = -3x / -3

3 = x

3 gulps

The distance from the center of an archery target to the outside edge of the target is 24 in. What is the diameter of the target

klemol [59]

Answer:

The diameter of the target is $48\ in$

Step-by-step explanation:

we know that

In this problem the distance from the center of an archery target to the outside edge of the target is equal to the radius of the target

$r=24\ in$

Remember that

The diameter is two times the radius

$D=2r$

substitute

$D=2(24)=48\ in$

(x-4)/5=9-(2x-41)/9

jok3333 [9.3K]

For this question, you have to take Least Common Multiplier for which in this case will be "45" as, the denominators can get similar and get multiplied by a same value to form a similar expression. This allows us to cancel out them by common factors. Full process shown below.

$\mathbf{Given \: \: Expression: \: \dfrac{x - 4}{5} = 9 - \dfrac{2x - 41}{9}}$

$\mathbf{\dfrac{x - 4}{5} \times 45 = 9 \times 45 - \dfrac{2x - 41}{9} \times 45}$

$\mathbf{9(x - 4) = 405 - 5 (2x - 41)}$

$\mathbf{9x - 36 = 405 - 10x + 205}$

$\mathbf{9x - 36 = - 10x + 610}$

$\mathbf{9x - 36 + 36 = - 10x + 610 + 36}$

$\mathbf{9x = - 10x + 646}$

$\mathbf{9x + 10x = - 10x + 646 + 10x}$

$\mathbf{19x = 646}$

$\mathbf{\dfrac{19x}{19} = \dfrac{646}{19}}$

$\mathbf{\therefore \quad x = 34}$

$\boxed{\mathbf{\underline{\therefore \quad Final \: \: Answer \: \: is; \: \: x = 34}}}$

Hope it helps.
