The domain of discourse is sets. Suppose some predicate Q is true for all elemenst of A: ∀a ∈ A Q(a). Recall the definition of s

Sloan [31]

Answer:

See the step-by-step explanation

Step-by-step explanation:

Let c be any element of C. (I'm not sure wether you have to assume that C is non-empt or not)

C is a subset of B. That means that as c is in C, it is also in B. ( $c \in C \Rightarrow c \in B$ )

Now, B is a subset of A. It follows that as $c \in B \Rightarrow c \in A$ .

That means c is an element of A. The predicate Q is true for all elements of A, including c.

Because we let c be any element of C, we have proven that the predicate Q is true for all elements in C.

Jimmy's school is selling tickets to the

natka813 [3]

Children’s tickets are $4, adult tickets are $14

Explanation:

4a+6c=80

If they made $4 more dollars on the second day than the first by selling one extra child ticket then we know a child’s ticket is $4 per ticket.

4a+6*4=80
4a+24=80
4a=56
14=a

So each adult ticket costs $14.

You can check by filling in $14 and $4 for each equation.

4*14+6*4=80

4*14+7*4=84
