Answer:
-0.5
Step-by-step explanation:
The cost of book has to be less than or equal to 26.39.
The amount of money Elena can buy has to be less than or equal to $30. Thus, the inequality sign to be used is the less than or equal to sign.
(1 + tax)cost of books + cost of bus fare ≤ value of the gift
1.08c + 1.5 ≤ 30
In order to determine the maximum cost of books, take the following steps:
Combine similar terms
1.08c ≤ 30 - 1.5
Add similar terms together
1.08c ≤ 28.50
Divide both sides of the equation by 1.08
c ≤ 28.50 / 1.08
c ≤ 26.39

Answer:
it would be x=17 1/2
Step-by-step explanation:
i am going to go a little more into detail.
you would first have to divide each side to isolate the variable
x=5/2/7
simplifying steps:
you would have to change the 5 into 5/1
5/1÷2/7
now you have to keep the first number, change the sign, and then flip the last number, AKA KCF
5/1*7/2
35/2
and you can simplify this into a mixed number
17 1/2
hope this helps! have a nice day :)
