I just told you the answer it is -5
Answer:
Rita = 300
John = 900
Rodell = 925
Step-by-step explanation:
rita = x (let
john = 3x ( john swims three times more than rita
rodell = 25 + 3x ( rodell swims 25 more than john
x + 3x + 25 + 3x = 2125
or, 7x + 25 = 2125
or, 7x = 2125 - 25
or, x = 2100/7
x = 300
hence,
x = 300
3x = 3 × 300
= 900
25 + 3x = 25 + 900
= 925
Answer:
D
Step-by-step explanation:
In Maths, axioms are basically set of propositions from which we can derive true statements from logic. Then these statements are known as theorems.
Hence, defining theorem in an axiomatic way means that a statements that we derive from axioms (propositions) using logic and that is proven to be true.
From the answer choices, we see D goes with this, hence D is the correct answer.
