Answer:
1555 people
Step-by-step explanation:
First, average the votes for polar bears.
(46 + 43 + 49)/3 = 46
Next, make the variable x equal to the estimate of the number of people who will prefer polar bear out of the 3380 people and set up your proportion equation.
x/3380 = 46/100
x = 1554.8
Round to the nearest whole number to get 1555.
I think the best answer is (-5x)+6y=36
When you add and subtract be sure that the two fractions have the same denomination, and then add/subtract the numerators. I always do cross multiplication of the two fractions to obtain the same denominators-although there are various ways to do this.
Multiplying fractions is simply straight across.
Dividing fractions:
Keep, change, flip.
Keep the first fraction the same, change the sign to its opposite (ex:division flips to multiplication), and flip the numerator and the denominator of the second fraction. Then, preform the arithmetic from your "new" problem.
Answer:
x = cd + b / a
Step-by-step explanation:
ax - b / d = c
ax - b = cd
ax = cd + b
x = cd + b / a
