Repeating decimals are considered rational numbers because they can be represented as a ratio of two integers. If a number is terminating or repeating, it must be rational if a decimal is both non terminating and non repeating, the number is irrational.
So yes.
(x+8)/10=(2x-5)/14
10*(2x-5)=14*(x+8)
20x - 50 = 14x + 112
20x - 14 x= 112 + 50
6x= 162
x= 162/6
x=27
Step-by-step explanation:
x=√7+√5, y=√7-√5
therefore, xy = (√7+√5)(√7-√5) = 7-5 = 2.
Hope this helps you.
Answer:
C
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
= -
Given the slope of the red line is 4 , then the slope of the green line is
m = - → C
0.27083333333 it would be this simplified which is 13/48
