38 + -38

always get rid of the plus sign when adding a negative to a positive.

38-38=0

15 + 23 = 38

therefore the answer would be -38

160 divided by 10 equals 16
16 x 3 =48
160- 48= 112
That should be right.

Ha. That looks alot like i-ready. (i-ready sucks butt.)

But the horror that is i-ready aside, your answer is the third one : The proportion of grandparents that feel safe entering their account information online is 0.32.

32% converted to a decimal is 0.32, and 68% converted to a decimal is 0.68. That would mean that the proportion for grandparents that feel safe doing so is 0.32, and the number of grandparents that don't feel safe doing so is 0.68.

10 people can paint a building in 5 days. if each person painted as quickly as the others then how much of the building could 7
Paul [167]
So basically it takes 10 people to paint a whole building. Forget about the 5 days. That's just there to confuse you. You have to first find out how much of a building can one person paint so, 1/10. So that means that 7 people can paint 7/10 of a building in 5 days
