4.5 times 10^10
1. Multiply 5times ten to the third
2. Multiply 9 times ten raised to the seventh
Then multiply them together
5000 times 90000000
The answer is -4.5
To solve these types of problems it's best to work backwards.
-2 - 16 = -18
4 x (n) = -18
n = -18/4
n = -4.5
The answer is C! the crossing of lines is the same on both sides
25 has 3 factors: 1, 5 and 25. Only those 3 numbers can be evenly divided into 25. 1 is a factor for every number, 5 can be divided into 25, 5 times and a number is always a factor of itself as well.
