Answer:
There are 400 possible zip codes in the Houston area 
Step-by-step explanation:
Here, we want to calculate the possible number of zip codes in the Houston area 
We have 5 digits to form
77 is the first two digits ( this is fixed)
For the third digit, we are selecting 1 number out of 0,3,4 or 5
This means 4 C 1 
The remaining digits can be any digits 
We have 0-9, a total of 10 digits 
The first will be 10 C 1 and the second last digit too is 10 C 1 
So the number of possible zip codes will be;
4 C 1 * 10 C 1 * 10 C 1
= 4 * 10 * 10 = 400 possible zip codes

Answer:
81
Step-by-step explanation:
12/3 = 4
4 - 2 = 2
x = 2
using the order of operations, you would first have to do y + 3
y = 12
12 + 3 = 15
the equation simplified is 3 x 2 + 5 x 15
3 x 2 = 6
5 x 15 = 75
75 + 6 = 81
