Answer:
Step-by-step explanation:
It has to be less than 6 , x+y<6
Now in inequalities that have 7 and 5 in them, 7 represents the cost of first ingredient and 5 the cost of second ingredient.multiply each of that number with quantity of that ingredient and sum both up we get the price of the mixture.
the mixture has to be less than 30 that means that it costs less than 30 but 30 can be the answer as well.
The last answer is 7x + 5y
-201+189=-12-201=-213+189=-24 . S the sign would be negative(-).

Answer:
The statement is false.
Step-by-step explanation:
Let a and b represent two odd integers.
The average (A) is defined by:
A=
In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.
Notice that it is easier to try to find a counterexample.
For example, a=3 and b=5
A= 
The result of the average is even, therefore the statement is false.
The previous calculation is a counterexample.
