There are 2076 people at a concert. One third of the people at the concert are under thirty years old. How many people are under thirty years old?

692

Step-by-step explanation:

To calculate of 2076, divide by 3, that is

people under 30 = 2076 ÷ 3 = 692

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
