Answer:
No, Monica did not correctly factor out the GCF
Step-by-step explanation:
The given expression is 
The prime factorization of each term are:
The greatest common factor is the product of the least powers of the common factors.
The greatest common factor is 6.
If we factor the GCF, we obtain:
Therefore Monica did not correctly factor out the GCF
People who purchased good seats will be labeled as a
people who purchased poor seats will be labeled as b
therefore...
5a + 2b = 660
a + b = 210
Now, all that has to be done is for the system to be solved.
-2(a+b=210)
5a + 2b = 660
-2a - 2a = -420
3a=240
a= 80
*3 people purchased good seats.
Now we can plug that number in
5(80) + 2b = 660
400 + 2b = 660
2b = 260
b = 130
*130 people purchased poor seats

Answer:
8182 kilometers
Step-by-step explanation:
A correct proportion to use is 22 over 5,000 = 36 over d
Cross multiply to get 22d = 5,000 x 36. Then, solve d. d = 8181.81.......so the approximate distance rounded to the nearest whole number from London to Beijing is 8182 kilometers.
Hope This Is Right.....
