Step-by-step explanation:

8.8 • 2.5 = 22 so I think 8.8 is the answer because the other options don’t make sense when multiplied by 2.5.

The judges at the track meet will award prizes to the top 4 teams. How many different ways can the top four teams place??
Nata [24]
They could give to teams more than likely on an average score the whole team has done, or at least that is what they are supposed to do. but they also might award the team which had more teammates get better places. for example if party place got three people on their team but they all did 3rd then boring barn who got 1 person could possibly win if that one person gets 1st place.

Twice the sum of three and a number is 30. Find the number
DedPeter [7]

9514 1404 393

Answer:

  • 2(x +3) = 30
  • 12

Step-by-step explanation:

When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:

  2(x +3) = 30 . . . . an equation for the given conditions

__

We can solve this equation by dividing by 2:

  x + 3 = 15

  x = 12 . . . . . . subtract 3

The number is 12.
