A set of numbers is shown below: {0, 0.6, 2, 4, 6} Which of the following shows all the numbers from the set that make the inequality 2x + 3 ≥ 7 true? {4, 6} {0, 0.6, 2} {0, 0.6} {2, 4, 6} Question 4 (Multiple Choice Worth 1 points) (08.05 MC) Meg scored 45, 48, and 56 on three tests. How many points should she get on the fourth test to get an average score of 60? 49.67 points 52.25 points 91 points 93 points

For the first one, we'll plug in the numbers in the set to see which ones will work.

3. OregonDuck

(2,4,6)?

4. anonymous

Yes, that would be it. Good job :)

Do you know how to get an average?

7. OregonDuck

yes

8. anonymous

So can you get the average of 45,48, and 46, and tell me what you get? :)

9. anonymous

Whoops, 56*

10. OregonDuck

49.6666666667

Right. Now we want the average of 4 tests to be 60. So we need the average to go up 10. So we can represent this with $\large \frac{45+48+46+x}{4}=60$ Now we need to get x alone

12. OregonDuck

x=91

Correct! Good job :)
