Answer:
-52.1
Step-by-step explanation:
-10/100 = -0.1
-0.1 x 20 = -2
-0.1 x 501 = -50.1
                   +    -2

Answer:
6. No. See explanation below.
7. 18 months
8. 16
Step-by-step explanation:
6. To rewrite a sum of two numbers using the distributive property, the two numbers must have a common factor greater than 1.
Let's find the GCF of 85 and 99:
85 = 5 * 17
99 = 3^2 + 11
5, 3, 11, and 17 are prime numbers. 85 and 99 have no prime factors in common. The GCF of 85 and 99 is 1, so the distributive property cannot be used on the sum 85 + 99.
Answer: No because the GCF of 85 and 99 is 1.

We can solve this problem with the lest common multiple. We need to find a number of a month that is a multiple of both 6 and 9.
6 = 2 * 3
9 = 3^2
LCM = 2 * 3^2 = 2 * 9 = 18
Answer: 18 months
We can also answer this problem with a chart. We write the month number and whether they are home or on a trip. Then we look for the first month in which both are on a trip.
Month                Charlie          Dasha
1                          home             home
2                          home             home
3                          home             home
4                          home             home
5                          home             home
6                         trip                home
7                          home             home
8                          home             home
9                          home             trip
10                         home             home
11                         home             home
12                         trip               home
13                         home             home
14                         home             home
15                         home             home
16                         home             home
17                         home             home
18                         trip                 trip
Answer: 18 months
8.
First, we find the prime factorizations of 96 an 80.
96 = 2^5 * 3
80 = 2^4 *5
GCF = 2^4 = 16
Answer: 16
