OverLord2011 [107]

A rotation is a rigid transformation, sometimes called an isometric transformation, that moves every point of the pre-image through an angle of rotation about the center of rotation to create an image. Rotations preserve size, rotations of 360 map a figure to itself, and lines connecting the center of rotation to the pre-image and the corresponding point on the image have equal length.

What is the solution set of the equation X/5 + x/2 =14?
JulijaS [17]

Answer:

x= 20

Step-by-step explanation:

Solve for x:

(7 x)/10 = 14

Multiply both sides of (7 x)/10 = 14 by 10/7:

(10×7 x)/(7×10) = 10/7×14

10/7×7/10 = (10×7)/(7×10):

(10×7)/(7×10) x = 10/7×14

10/7×14 = (10×14)/7:

(10×7 x)/(7×10) = (10×14)/7

(10×7 x)/(7×10) = (7×10)/(7×10)×x = x:

x = (10×14)/7

14/7 = (7×2)/7 = 2:

x = 10×2

10×2 = 20:

Answer:  x = 20
