The answer is 50. You add all of the numbers in the data set, and divide it by the number of numbers in the data set. the sum of all of the numbers is 350, divide that by 7( the amount of numbers in the data set) and you get 50
First you need to change the equation to 3 < x/2 + 1
then we can treat it like a normal equation.
subtract 1 from each side to get 2 < x/2
then multiply both sides by 2 to get rid of the fraction and we have
4 < x and we switch it around to get
x > 4 as our answer! :)
C. an isosceles triangle has 2 equal sides.
the reason b and d aren’t true is because the sides add up to be less or equal to the longest side and to make a triangle the 2 sides have to add up to be more than the longest side.
