Answer:
add 1/4 to each side
Step-by-step explanation:
x^2+x=11
We take the coefficient of the x term
1
Then divide it by 2
1/2
Then square it
(1/2) ^2 = 1/4
Add this to both sides of the equation
x^2 + x + 1/4 = 11+1/4
(x+1/2)^2 = 11 1/4
Answer:
39 students
Step-by-step explanation:
In order to solve this you need to first set up a proportion with x equaling the number of students who voted for the athlete, 65/100 = x/60. 65/100 represents 65% and it is equal to a certain number of students out of 60. To solve for x you need to cross multiply so you would have 100x=65(60), simplified this would be 100x=3900, then you divide both sides by 100 to get x over 39. So, 39 students voted for the athlete.
