Solve for a: b − 2a = c

vlada-n [284]

Answer:

$a=-\frac{c-b}{2}$

Step-by-step explanation:

Solving for the variable $a$ , given that :

$b-2a=c$

We can first start start by subtracting $b$ from both sides of the equation:

$-2a=c-b$

Now, we can divide both sides of the equation by the coefficient of $a$ , which would be $-2$ :

$a=\frac{c}{-2}-\frac{b}{-2}$

Applying the fraction rule $\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}$ :

$a=\frac{c-b}{-2}$

Then, apply the fraction rule $\frac{a}{-b} =-\frac{a}{b}$

$a=-\frac{c-b}{2}$

One difference between an assembly line process flow and a continuous process flow is that on the assembly line the flow is disc

IgorLugansk [536]

Answer:

True

Step-by-step explanation:

Assemble line is a production process in which parts are joined to the products produced as a partially finished product.

Here the process flow is discreet that is assembled one at a time.

Continous process flow is a type of manufacturing products without disruption of the flow process.

As the name implies,it is continous.

Answer: 3x sq. root of 648^x*2^3+2y

Step-by-step explanation:

3x square root of 648x^4y^8

you do something to the 4 and eight

math is complicated and your teacher will most likely not check it

as long as it looks intelligible

4/8 = 2

idk

there's the possibility that the expression cant be simplified
