You can simplify expressions by simplifying parentheses by using the distributive property and combing like terms.
Combining like terms is the process of adding up numbers with the same variable(s) and exponent. If a term does not have an exponent then an exponent of 1 is implied.
There is no parentheses in the expression 3a + 7 - a - 7
But, there are like terms in the expression.
Which are the like terms?
3a and a are both like terms. They both have the same variables and they both have the same exponent.
7 and -7 are like terms, too.
3a + 7 - a - 7
2a
So, 2a is the simplified version.
Step-by-step explanation:
6 --- 2
9= 5
16=9
24= 19

Deli B has the better deal
Since 2 pounds cost 19.98, one pound would be 9.99 at Deli A
At Deli B, 3 pounds cost 23.97, meaning one pound costs 7.99
The quotient of 3 and 3/5 divided by 2/5 is 0.134
