25 is the answer because 4 to the second power is 8 and then six times four is 24 then subtract 24 - 8 then add 9 and you will get 25!

Solve the literal question 2a-b.=8b-4a for a

Anna71 [15]

Just good ole algebraic manipulation
$2a - b = 8b - 4a$
First, Let's Combine Common Terms

$(2a + 4a) = (8b + 1b) \\ 6a = 9b$
Now Let's Divide

$\frac{6a}{6} = \frac{9b}{6} \\ a = \frac{9b}{6}$
Let's Simplify That Fraction

$a = \frac{9}{6} \times \frac{b}{1} \\$
Answer

$a = \frac{3b}{2} \:$

Answer:

$50

Step-by-step explanation:

x is distance and y is cost because the cost is dependent on the distance which makes the distance the independent variable. you can always use y=mx+b for these problems!!

8xy= 2(2x + y) solve for y

STatiana [176]

Answer: $\displaystyle y= \frac{2\text{x}}{4\text{x} - 1}$

============================================

Work Shown:

$8\text{x}y= 2(2\text{x} + y)\\\\8\text{x}y= 4\text{x} + 2y\\\\8\text{x}y - 2y= 4\text{x}\\\\y(8\text{x} - 2)= 4\text{x}\\\\y= \frac{4\text{x}}{8\text{x} - 2}\\\\y= \frac{2*2\text{x}}{2(4\text{x} - 1)}\\\\y= \frac{2\text{x}}{4\text{x} - 1}\\\\$

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

Explanation:

The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.

Then factor out y and divide both sides by (8x-2)

Afterward there's the optional steps of simplifying (as shown in the final two steps).
