It is rational. Any number that can be described as a fraction is rational while those that do not are irrational.
-0.28764 is the same as -(28764/100000) and positive, negative does not matter.
Answer:
14x + 5 = 31
x= 13/7
2x - 3y = -29
=2x - 3y +29 =0
Step-by-step explanation:
14x + 5 = 31
first step move the +5 to the other side beside the 31 it will become -5
Then subtract the numbers 31-5 =26
14x=26
Divide both sides by 14
x= 13/7
The distance from D to the closest point on either side will be ...
... (8 ft)·sin(60°/2) = 4 ft
Both distances are 4 ft.
_____
It isn't really clear that you don't want the distance along line BC; rather, you want the direct shortest distance to the side. For that, sufficient information is given.
D. 4/7
Distance from 0 is absolute value. We take the absolute values of all of these and convert them to decimals so we can compare them to each other more easily.
A. |-3/8|=3/8=0.375
B. |-0.3|=0.3
C. |0.27|=0.27
D. |4/7|= about 0.57
Thus, D is the furthest because it has the greatest absolute value.
