20 + 5 + 500,000,000 = 500,000,025
500,000,025 - 200,000 = 499,800,025
So Johny has 499,800,025
Tommy has 100,005
And Tommy's sister has 100,020
Hope it helps!
Answer:
b. The range only includes numbers greater than or equal to 0.
Step-by-step explanation:
Any square of a number will never lead to a negative number
The range of an equation is it's numerical possibilities for y
Since a square of a negative number never leads to a negative y
The answer is therefore, the range can only be zero and above
(otherwise the roots would be imaginary)
I would say the 3rd one but I don’t know.
15 + 0.10n = 0.25n
15 = 0.25n - 0.10n
15 = 0.15n
15 / 0.15 = n
100 = n....they are the same at 100 brochures
