Answer:


Step-by-step explanation:
Let A represent number of adult t-shirts and C represent number of child t-shirts.
We have been given that adults t-shirt are $5 child t-shirt are $2.50, so cost of A adult t-shirts would be
and cost of C child t-shirts would be
.
We have been given that Jerome need at least 200 adults t-shirt. This means the number of adult t-shirts should be greater than on equal to 200.
We can represent this information in an inequality as:

We are also told that Jerome will spend no more than $1500 on t-shirt. This means that cost of A adult t-shirts and C child t-shirts should be less than or equal to 1500.
We can represent this information in an inequality as:

Therefore, our required system of inequalities would be:


Answer:
x = 
Step-by-step explanation:
Given
3(x - 6) = 6 + 7, that is
3(x - 6) = 13 ← distribute parenthesis on the left side by 3
3x - 18 = 13 ( add 18 to both sides )
3x = 31 ( divide both sides by 3 )
x =

Answer:
f(12) = - 20
Step-by-step explanation:
To evaluate f(12), substitute x = 12 into f(x), that is
f(12) = - 2(12) + 4 = - 24 + 4 = - 20
