Answer:
x=-25.5
Step-by-step explanation:
5/2(-13) +7=-25.5
A) 2.025 x 10^14 kilometers / 225 million years
B) 2.25 × 10^8
C) 2.025 x 10^14 kilometers / 2.25 x 10^8 years
D) 2.025 x 2.25 = .9
E) 10^14 - 8 = 10^6
F) .9 x 10^6
Notes:
To write in scientific notation, move the decimal place over until there is only 1 number outside of it. (25,000 now equals 2.5) Then count how many spaces you moved over (25,000 moved over three zeros, and the five. That is 4 places) that is what you use to put over the 10 (2.5 x 10^4 = 25,000)
Here. I hope you can see it.
The answer would be D and E
Explanation: the number line shows any number less than 16, the filled in circle also means including 16. So it becomes any number 16 or less. So in both of the scenarios the max number of either students or dollars has to be 16.
Hope this helps
