Question

I need help on this question would you be able to help me?

Answer 1

Part a.

Let x be the unknown number. Then, the statement "the product of a number and 2" can be written as

`2x`

since this product must be equal to 16, we have

`2x=16`

Then, the answer is the second option: 2x=16.

Part b.

In this case, we need to isolate the x variable. Then, by dividing both side of our last result, we get

`x=(16)/(2)`

which gives

`x=8`

Therefore, the answer for b) is: 8
