-3x+13=16

Move +13 to the other side. Sign changes from +13 to -13.

-3x+13-13=16-13

-3x=16-13

-3x=3

Divide by -3 for both sides.

-3/-3x=3/-3

Cross out -3 and -3, divide by -3, then becomes 1*1*x=x

x=-1

Answer: x=-1

How to get the answer to 2/3(3x+6)=4x+3 without using distributive property.
Annette [7]

The answer for the given equation is x = 3.5.

<u>Step-by-step explanation</u>:

Given, 2 / 3 (3x + 6) = 4x + 3

Step 1:

Rearranging the given equation by subtracting the right side of the equation to the left side.

                           2 / 3 (3x + 6) - 4x + 3 = 0

Step 2:

Taking out the like terms, the equation becomes

                          (2 / 3) \times 3 (x + 2) - (4x - 3) = 0

                          ⇒   2 (x + 2) - (4x - 3) = 0

Step 3:

Solving the equation for the value of x,

                          ⇒    2x + 4 - 4x + 3 = 0

                          ⇒    -2x + 7 = 0

                          ⇒     -2x = -7

                          ⇒     x = 7 / 2 = 3.5.

Hence the value of x = 3.5.

Help!!!!! please!!!!!
iren [92.7K]

Answer:

Step-by-step explanation:

r = 15 ft

h = 22 ft

Volume of cylinder = πr²h

                                = π * 15 * 15 * 22

                                = 4950π

                                = 4950 * 3.14

                               = 15543 cubic ft

What is the value of (g*h)(-3)?
slega [8]
ANSWER


\boxed {(g \circ \: h)( - 3) =  \frac{ 8}{ 5}}



EXPLANATION

The given functions are:


g(x) =  \frac{x + 1}{x - 2}


and

h(x) = 4 - x


Let us find

(g \circ \: h)(x)


This implies that,


(g \circ \: h)(x) = g(h(x))


(g \circ \: h)(x) = g(4 - x)


(g \circ \: h)(x) =  \frac{4 - x + 1}{4 - x  - 2}


(g \circ \: h)(x) =  \frac{5- x}{2 - x }



We now substitute x=-3


(g \circ \: h)( - 3) =  \frac{ 5 -  - 3}{ 2 -  - 3}



(g \circ \: h)( - 3) =  \frac{ 8}{ 5}


The correct answer is A
