3/4 because you can simplify them by dividing both by 4 to get 3/4. If you don't know what factors the two share make a list of the factors of each and divde by the biggest number they share.

Cancel the common factor: 4
=3/4
12 is 3/4 or 75% of 16

Ms. Thomas took her family and friend to the movies. There were a total of 16 people. Children tickets cost $6 and adult tickets

Korolek [52]

Answer:

11 adults

Step-by-step explanation:

First, set up a system of equations:

Let x = number of children and y = number of adults

There is a total of 16 people, so x+y = 16. This is your first equation.

Each child ticket costs $6, so 6x = cost of children's tickets based on the number of children present (x)

Each adult ticket costs $9, so 9y = cost of adult's tickets based on the number of adults present (y)

The total cost of tickets is $129, so 6x+9y = 129. This is your second equation.

Your system of equations is now this:

x + y = 16

6x + 9y = 129

You can solve this system using the method of elimination, where we will eliminate the variable x (number of children), since we are focused on y (number of adults).

Multiply the top equation by -6. This will give the following equation:

-6x - 6y = -96

You can now solve the system of equations by placing the new equation under the second equation like this:

6x + 9y = 129

-6x - 6y = -96

Now, add the two equations together.

6x + (-6x) = 0

9y + (-6y) = 3y

129 + (-96) = 33

After doing this, you get the following equation:

3y = 33

As you can see, the variable x has been eliminated, and you are left with y.

Solve the equation for y:

3y = 33

y = 33/3 = 11

y = 11 adults

Point T is on line segment \overline{SU} SU . Given TU=4x+1,TU=4x+1, SU=8,SU=8, and ST=3x,ST=3x, determine the numerical length

zysi [14]

Answer:

Step-by-step explanation:

If point T is on the line SU, then ST+TU = SU. Given TU=4x+1, SU=8, and ST=3x

Substituting the given values into the expression ST+TU = SU

8 = 3x+4x+1

8 = 7x+1

collect like terms;

7x = 8-1

7x = 7

Divide through by 7

7x/7 = 7/7

x = 1

Substitute x = 1 into the expression TU = 4x+1 to get the length of TU

TU = 4(1)+1

TU = 4+1

TU = 5

<em>Hence the length of TU is 5</em>

What is the answer for -5x^2=-500 by factoring the quadratic equation?

evablogger [386]

Answer:

x=10

Step-by-step explanation:

I think..i tired

Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

Simplify \frac{500}{5}5500 to 100100.

{x}^{2}=-100x2=−100

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

Simplify \sqrt{-100}√−100 to \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.

Saved Suppose that the population of deer in a state is 1,500 and is growing 2% each year. Predict the population after 4 years.

mestny [16]

<h2>Steps</h2>

So for this, we will be creating an equation using the exponential formula - which is $y=ab^x$ (a = initial value, b = growth/decay).

Firstly, we know that the original population of the deer is 1,500 so that will be our a value.

Next, we know that the population is growing by 2% annually. With this, we will <em>add</em> 1 and 0.02 (2% in decimal form) since the population is <em>increasing</em>.

1 + 0.02 = 1.02

1.02 will be our b variable. Now putting it together, our equation is: $y=1500(1.02)^x$

Now that we have our equation set up, plug 4 into the x variable and solve for y as such (Remember to not round until the very end):

$y=1500*(1.02)^4\\y\approx 1624$

<h2>Answer</h2>

<u>After 4 years, the deer population will be 1,624.</u>
