9. Let p be "an animal is a dog" and let q be "an animal is a golden retriever." Write the conditional statement. Then decide whether it is true or false.

a. If an animal is a golden retriever, then it is a dog; true

b. If an animal is not a golden retriever, then it is not a dog; false

C. If an animal is a dog, then it is a golden retriever; false

If an animal is not a dog, then it is not a golden retriever; true

C. If an animal is a dog, then it is a golden retriever; false

Step-by-step explanation:

Logical reasoning is an important aspect of mathematics.

The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.

In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60
