Twice as many students go to the park than to the theater. Five more students go to the theater than to the museum. If 16 studen

Lemur [1.5K]

Answer:

3 students

Step-by-step explanation:

Twice as many students go to the park than to the theater :

Let number who go the theater = t

Number who goes to park = 2t

5 more students go to the theater than to the museum

Number who goes to museum = t - 5

If number of students who goes to park = 16

How many students goes to the museum :

2t = 16

t = 16/2

t = 8

Number who goes to museum = t - 5

t - 5 = 8 - 5 = 3

Hence, number of students who goes to the museum = 3

What is the factorization of 3x2 – 8x + 5?

ELEN [110]

we have

$3x^{2} -8x+5$

Equate the expression to zero to find the roots

$3x^{2} -8x+5=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$3x^{2} -8x=-5$

Factor the leading coefficient

$3(x^{2} -(8x/3))=-5$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$3(x^{2} -(8x/3)+(16/9))=-5+(16/3)$

$3(x^{2} -(8x/3)+(16/9))=(1/3)$

Rewrite as perfect squares

$3(x-(4x/3))^{2}=(1/3)$

$(x-(4x/3))^{2}=(1/9)$

square roots both sides

$(x-\frac{4}{3})=(+/-) \sqrt{\frac{1}{9}}$

$x=\frac{4}{3}(+/-) \frac{1}{3}$

the roots are

$x=\frac{4}{3}+ \frac{1}{3}=\frac{5}{3}$

$x=\frac{4}{3}- \frac{1}{3}=\frac{3}{3}=1$

$3x^{2} -8x+5=3(x-\frac{5}{3})(x-1)=(3x-5)(x-1)$

therefore

<u>the answer is the option</u>

$(3x-5)(x-1)$
