216 = 6^3

216 = 6^(4x + 11)

6^3 = 6^(4x + 11)

3 = 4x + 11

4x = 3 -11

4x = - 8

x = -2

Answer:

the value of x=-2

Step-by-step explanation:

$216=6^{4x+11}$

To solve for x we need to make the same base on both sides

we need to get same base 6 on both sides of the equation.

216 can be written as 6 times 6 times 6 =6^3

$6^3=6^{4x+11}$

Both sides have same base, so we equate the exponents

$3=4x+11$

Subtract 11 on both sides

$-8=4x$

Divide both sides by 4

$-2=x$

So the value of x=-2

Solve -5 + w divided by 3 = -1. 12 -12 2 -2

son4ous [18]

Hello!

Answer:

w=12

*The answer must have a positive sign.*

Step-by-step explanation:

First, you add by 5 from both sides of an equation.

$-5+\frac{w}{3}+5=-1+5$

Then, you simplify.

$\frac{w}{3}=4$

Next, you multiply by 3 from both sides of an equation.

$\frac{3w}{3}=4*3$

And finally, simplify and solve. You can also multiply by the numbers from left too right.

$4*3=12$

Final answer: → $w=12$

Hope this helps!

Thanks!

Simplify (3x+2)(x-7)

vovangra [49]

The answer is
$3 {x}^{2} - 19x - 14$
first you must multiply or use the FOIL method (First, Outer, Inner, Last)
First you multiply the first terms
$(3x)(x)$
this gives you 3x^2, then you multiple the outer terms
$( - 7)(3x)$
this gives you -21x, then you multiply the inner terms
$(2)(x)$
that gives you 2x, finally you multiply the last terms
$(2)( - 7)$
that gives you 14, now you combine like terms
$- 21x + 2x = - 19x$
now you put all the terms together and end up with your solution
$3 {x}^{2} - 19x - 14$

Thorazine is available in a strength of 25 mg/mL. Express this strength as a percent.

wolverine [178]

Answer:

2.5%

Step-by-step explanation:

Thorazine is available in the strength of 25mg/mL.

To find out the percentage strength,

W/V = g/mL (weight in grams of solute/milliliters of solute.)

1mL of Thorazine contains 25mg.

Dissolve Thorazine with the 100mL solution.

Therefore, 25 x 100 = 2500mg

Which is equals to 2.5g

100mL solution contains 2.5g of Thorazine.

Percentage Strength (W/V) = 2.5 / 100 x 100 = 2.5%.

The percentage strength of Thorazine 25mg/mL has 2.5%
