Ten of the thirty students on the bus were boys. What percentage of the bus's travelers were boys?

33.33%

Step-by-step explanation:

Out of 30 students, if 10 were boys, the fraction would look like:

10/30

After converting the fraction to a decimal, the answer would turn out as 33.33% :)

The percentage is 33.33%

Step-by-step explanation:

Put x over 100 because x represents the percentage. Next, you put 10 over 30.

Cross multiply so 100 time 10. And then 30 times x. So now you have

30x=1000 Divide that and you get 33.33%

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
