Three consecutive natural numbers have a sum of 30. what is the least number?

Consecutive numbers are 1 away from each other
they are
x,x+1,x+2

sum is 30
x+x+1+x+2=30
3x+3=30
minus 3 from both sides
3x=27
divide both sides by 3
x=9
x+1=10
x+2=11

the least number is 9

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

The reporter forgot to multiply the decimal by 100, making it 25%
