The sum of any two rational numbers is a rational number. 0.166, 2/3, and 2 are all rational numbers, so adding them to 1/3 will produce another rational number.
That leaves 2π, an irrational number. The sum of a rational number and an irrational number is always irrational, so 2π will produce an irrational number when added to 1/3.
Answer:
Edna = 56.5
Elsa = 57.5
Step-by-step explanation:
Represent Edna age with x; Elsa age will be x + 1
So,


Make 2x the subject


Solve for x


Elsa age is calculated as thus;



The bottom right graph is correct. x must fall between 3 and 6, so that automatically rules out the bottom left, as one of the points falls on 2.
the top left is incorrect because it doesn't show that x is greater than or EQUAL to three. it has an open circle rather than a closed circle. that's two answer choices eliminated.
from there, you just have to refer back to your given information:
<span>3≤x≤6
the given info says that x must be between or equal to 3 and 6. the top right graph leaves out a "step" because it has 5 and 6 as solid dots side by side.</span>
Answer: 3/2
Step-by-step explanation:
1= 2/2. 2/2 + 1/2 = 3/2
