Ms.Sue... Steve or any other tutor that deals with math.. can you see if my answers are correct?

• URGENTquestions for Math - ,

1. p - .25p
= 40 - .25(40)
= 40 - 10 = 30 , so A

2. correct

3. 5^2 - 4/5 + 2
= 25 - .8 + 2
= 26.2 , correct

4. (t^3 - r + 20) /4 , when r=4, t=2
= (8 - 4 + 20)/4
= 24/4 = 6 , so C
