In a school election, Yolanda got 160 more votes than Alex, and Alex got twice as many votes as Jennifer. A total of 440 votes were cast.

Let votes of Jennifer be x

Total votes = x+(x*2)+(x*2+160)

440=x+2x+2x+160

440-160=5x

x=280/5=56

Votes of Jennifer= 56

votes of Alex= 56*2= 112

votes of Yolanda= 112+160= 272

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
