1. Translate the following phrase to an expression: the difference between twenty and twice a number.

20 - n
20 - 2 n
20 + 2 n
2 n - 20

2. Translate the following phrase to an expression: the difference between twenty and twice a number.

Evaluate the expression for n = 3.

17
3
14
26

3. Ifh=27, what is the value ofh÷9?

243
3
18
36

Step-by-step explanation:

1. The difference of means that we are looking at subtraction. Now, we can eliminate the 3rd option because that has addition. Now, let's find the numbers that are being subtracted. Let's call the number n. This means that twice a number is 2n, which eliminates the first option because it has n, not 2n. We know that 20 and 2n are being subtracted, but in which order? Since 20 was stated before 2n, we know that 20 comes first and 2n comes second. The only option that has this is the second one, 20-2n.

2. We use the expression obtained in the last question, 20-2n. Now, we plug in 3 for n, and when we do so, we get 20-2*3 = 20-6 = 14, the third option.

3. We know that h=27 and we want to find the value of h/9. To do this, we simply plug in 27 for h into h divided by 9, and we get 27/9 = 3, the second option. Hope this helps!
