What is the value of x?<br><br> x = ___

gregori [183]

Answer:

10

Step-by-step explanation:

To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.

$\frac{12}{2x+1}=\frac{8}{x+4}$

To solve for x, cross multiply:

12(x+4) = (2x+1)(8)

12x + 48 = 16x + 8

48 = 4x + 8

40 = 4x

10 = x

Let a,b,,c and x elements in the group G. In each of the following solve for x in terms of a,b,c, and c.

Alchen [17]

Answer with Step-by-step explanation:

We are given that a, b, c and x are elements in the group G.

We have to find the value of x in terms of a, b and c.

a. $x^2a=bxc^{-1}$

$x^2ac=bxc^{-1}c=bx$

$x^{-1}x^2ac=x^{-1}bx=b$ ( $x^{-1}bx=b$ )

$xac=b$

$xacc^{-1}=bc^{-1}$

$xa=bc^{-1}$ ( $cc^{-1}=$ )

$xaa^{-1}=bc^{-1}a^{-1}$

$x=bc^{-1}a^{-1}$

b. $acx=xac$

$acxc^{-1}=xacc^{-1}=xa$ ( $cc^{-1}=1,cxc^{-1}=x$ )

$axa^{-1}=xaa^{-1}$ ( $aa^{-1}=1,axa^{-1}=x$ )

$x=x$

Identity equation

Hence, given equation has infinite solution and satisfied for all values of a and c.
