What is a / b (2x - 12) = c / d ; x ?

Alex17521 [72]

we are given

$\frac{a}{b} (2x-12)=\frac{c}{d}$

we can solve for x

We can isolate x

step-1: Multiply both sides by b/a

$\frac{b}{a}*\frac{a}{b} (2x-12)=\frac{b}{a}*\frac{c}{d}$

$(2x-12)=\frac{bc}{ad}$

step-2:Add 12 both sides

$(2x-12)+12=\frac{bc}{ad}+12$

$2x=\frac{bc}{ad}+12$

step-3: combine right side

$2x=\frac{bc+12ad}{ad}$

step-4:Divide both sides by 2

$x=\frac{bc+12ad}{2ad}$ ..............Answer

Write a power represented with a positive base and a positive exponent whose value is less then the base

sasho [114]

Answer:

The question is open ended as i suppose since there are infinitely many possibilities. one possible form of the solution can be $5^{2}$

Step-by-step explanation:

The base in this case is 5 while the exponent is simply the power to which the base is raised in which case it would be 2. Both values are positive and the exponent is less than the base.
