Answer:

(B) It decreases

Step-by-step explanation:

I figured this out with basic logic, but we can use proof to find it out.

If we have 35+k, we can assume that k is around 10.

So 35+10=45.

Now let's decrease k by 1, making k=9.

35+9=44

We can see that the value is decreasing, but let's try one more.

Let's make k=8.

35+8=43

So we can see the general pattern here is that it's decreasing.

Hope this helped!

Answer:

  (C)  Step 1: 15x − 20 = 1; Step 2: 15x = 21

Step-by-step explanation:

The first step is to eliminate the parentheses, using the distributive property.

  5(3x − 4) = 1

  15x -20 = 1

The second step is to add 20 to both sides of the equation.

  15x = 21

This pair of steps is shown in the 3rd choice.

_____

<em>Comment on the answers</em>

The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.
