This question is killing me plz help

Males:

10.4% have green eyes.

33.3% have blue eyes.

56.3% have brown eyes.

Females:

7.5% have green eyes.

47.5% have blue eyes.

45% have brown eyes.

Explanation:

To find each percentage, we have to count up the amount of people for each gender.  When we have the males, we add them up and we get 48 males.  Now lets take green eyes and divide it by 48, since 5 ÷ 48 0.1041666666666667, we now multiply that number by 100 and we get 10.41666666666667.  Now round that number to the nearest ten and we get %10.4.  Now you know the formula, I hope you understand it. :)

45

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
