Answer:the expression is 5x - 2
Step-by-step explanation:
The number of customers in a store on the first day is represented by: (6x - 3).
The number of customers on the second day is represented by: (x - 1)
An expression to find how many more customers visited the store on the first day would be the difference between the number of customers that visited the store on the first day and the number of customers that visited the store on the second day. The expression becomes
6x - 3 - (x - 1)
= 6x - 3 - x + 1
= 6x - x - 3 + 1
= 5x - 2
1st multiply 2 x 8 x 144 = 2304 in^3divide 2304 by 144 = 16 board feet
Answer:
Consider the expression 
. q is called the quotient, a is is the dividend and b is the divisor.
Since q is a multiple of 6, then q has the form 
for some integer k.
Since a is a multiple of 9, then a has the form 
for some integer s.
Since b is a factor of 12, then if 12 can be expressed of the form 
, for c an integer. Then b has the form 
Replacing the preview expression in the initial expression we obtain:
Then 
is a equation to Isabel's problem.
