<u>Answer</u>

6


<u>Explanation</u>

let n be the first even number in the sequence.

The 2nd term = n + 2

       3rd term = n + 2 + 2

                       = n + 4

    4th term = n + 4 + 2

                   = n + 6

The sum of these number = 36.

∴ n + (n +2) + (n + 4) + (n + 6) = 36

 4n + 12 = 36

 4n = 36 - 12

 4n = 24

n = 24/4

  = 6

The first term is 6.

37 1/2 is what percent of 5
DanielleElmas [232]

Answer:

750%

Step-by-step explanation:

We know that 100% of 5 is 5,

200% of 5 is 10,

300% of 5 is 15,

400% of 5 is 20,

500% of 5 is 25,

600% of 5 is 30,

700% of 5 is 35,

800% of 5 is 40.

So 37 1/2 percent of 5 must be between 700 and 800 percent of 5. We also know that 2.5 is 50% of 5, and 35 + 2.5 = 37.5. So 37 1/2 is 750% of 5
