To round 30.72 to the nearest tenth, or the place value where you have the value of 0.7 in, look to the value right of the 7, or the value of 2.

Because it is closer to the value of 0, you would round down, meaning that 30.72 rounded to the nearest tenth would be 30.7, which is your answer.

The sum of two consecutive odd integers is at least 16

elena-14-01-66 [18.8K]

Odd integers are represented by 2n+1 where n is a whole number

consecutive odd are 2 apart so
they are 2n+1 and 2n+1+2

the sum of them is at least 16
2n+1+2n+1+2>16
4n+4>16
minus 4
4n>12
divide 4
n>3
sub back

2n+1 and 2n+3
2(3)+1 and 2(3)+3
6+1 and 6+3
7 and 9

they have to be at least 7 and 9
