4 0

1. 22 students is 40% of 55

2. 24 red marbles is 40% of  60 marbles

3. 15% of $9 is $1.35

4. 12 is 6% of 200

5. Bethany sent 9 text messages to her friend yesterday.

6. There where 17.01 people in the survey.

7. The sales tax rate is 6.5%.

8. There were 10(0.1) from 18-29 that voted in the election.

9. There were 35(0.35) from 50-64 that voted in the election.

10. There were 25(0.25) of over 64 year old's that voted in the election.

11. Sahli  is incorrect because there is 30 people within ages 30-49. I think he came up with that answer so quickly because 30 + 49 = 1470 and divided by 14 = 105 with this you add 30 and get 135.

(3x+13)^1/2-5=x. check for extraneous soultions
kondor19780726 [428]
Both of the solutions, x = {-4, -3}, are viable. There are no extraneous solutions.


_____
An extraneous solution would show up as the x-intercept associated with the missing branch of the square root function. Since both solutions are on the positive-square-root branch, they are both good solutions to the equation.

For graphing purposes, we have subtracted x to get
   f(x) = √(3x+13) -5 -x
and we are looking for solutions to f(x)=0.


If you add 5 and square both sides, you get the quadratic equation
   3x +13 = (x +5)²
   x² +7x +12 = 0
   (x +3)(x +4) = 0
   x ∈ {-4, -3}
