If 2x+8=16, what is the value of x+4?

True [87]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{8}}}}}$

Step-by-step explanation:

<u>First</u><u>,</u><u> </u><u>finding </u><u>the </u><u>value</u><u> </u><u>of</u><u> </u><u>x</u>

$\sf{2x + 8 = 16}$

Move 8 to right hand side and change it's sign

$\dashrightarrow{ \sf{2x = 16 - 8}}$

Subtract 8 from 16

$\dashrightarrow{ \sf{2x = 8}}$

Divide both sides by 2

$\dashrightarrow{ \sf{ \frac{2x}{2} = \frac{8}{2} }}$

Calculate

$\dashrightarrow{ \sf{x = 4}}$

Value of x is 4

<u>Now</u><u>,</u><u> </u><u>Substituting</u><u> </u><u>/</u><u> </u><u>Replacing </u><u>the</u><u> </u><u>value </u><u>of</u><u> </u><u>x</u><u> </u><u>in</u><u> </u><u>order</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>x</u><u>+</u><u>4</u>

<u> $\sf{x + 4}$ </u>

plug the value of x

$\dashrightarrow{ \sf{4 + 4}}$

Add the numbers : 4 and 4

$\dashrightarrow{ \sf{8}}$

Hope I helped!

Best regards! :D

A chemist wants to mix a 66% alcohol solution with eight liters of 54% alcohol solution to produce a solution that is 65% alcoho

Rzqust [24]

Answer:

We have 8 liters of 54% alcohol.

We will add "x" liters of 66% alcohol to make "8 +x" liters of 65% alcohol.

54 * 8 + 66 x = 65 (8 + x)

432 + 66x = 520 + 65x

x = 88 liters

What is the answer to this math equation(x+5)(x²-3x)

Nikolay [14]

Answer:

$x=-5\\x=0\\x=3$

Step-by-step explanation:

I assume your equation to solve is

$(x+5)(x^2-3x)=0$

When we have a product of two factors equal to zero,

$A\cdot B = 0$

The solution is either A = 0 or B = 0.

In this case, this means that we can break the equation into two equations:

$x+5=0\\x^2-3x=0$

Solving the first one, we get:

$x+5=0 \rightarrow x = -5$

For the second one, we rewrite it as:

$x^2-3x=0\\x(x-3)=0$

And we see that this equation has two solutions:

$x=0\\x=3$

Therefore, the three solutions are:

$x=-5\\x=0\\x=3$
