Prime numbers are not divisible by any number but themselves or 1.
A) 115 is divisible by 5, so it is not prime
B) 273 is divisible by 3 (you get 91), so it is not prime
C) 317 is prime! only divisible by itself or 1
D) 414 is divisible by 2, so it is not prime. Even numbers are never prime because they are divisible by 2!
Answer:
x=260 texts
Step-by-step explanation:
85=0.25x+20
Subtract 20 from each side.
65=0.25x
Divide both sides by 0.25.
260=x
260 texts plus the $20 flat fee will cost $85.
Since both objects are assumed to have the same volume, matching the formulas we'll get:
π

h =

π

h
Having both <span>π and h at both sides of the equation, we can ignore them, so:
</span><span>

=


</span>
And clearing R, according to the equation rules, we'll get:
= R
Answer:
3.7 miles per day
Step-by-step explanation:
At x = 8, y = 4
At x = 14, y = 7
At y = 3, x = 6
Solution:
Given rule:

At x = 8,

Hence at x = 8, y = 4.
At x = 14.

Hence at x = 14, y = 7.
At y = 3

Multiply by 2 on both sides.


Hence at y = 3, x = 6.
