The 3rd one

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

set up a proportion:

24 = 32

 33     32+x

24(32 + x) = 32(33)

768 + 24x = 1056

24x = 288

x = 12

Answer:

D. [tex]\displaystyle (x - 5)^2 = 36[/tex]

Step-by-step explanation:

All you are doing is converting this Quadratic Equation to a Vertex Equation in Vertex Form by completing the square:

[tex]\displaystyle [\frac{b}{2}]^2 \\ \\ x^2 - 10x - 11 = 0 → x^2 - 10x + 25 - 36 = 0→ (x - 5)^2 - 36 = 0 \\ \\ (x - 5)^2 = 36[/tex]

It is that simple, is it not?

when you multiply 4 x 2 you get 8 and when you divide 3 x 2 you get 6

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

Answer:

Step-by-step explanation:

sure lizzie  

soo  elimination method just means we want to cancel out on of the variable by subtracting of add the entire equations to each other... there is another method but this one is pretty good to learn with.

system 1

2x + 2y = -2

3x - 2y = 12

since there is already an easy way to get rid of the y variable lets just add the two equations together, just add term by term

5x  + 0y = 10

if you notice .. just by making an imaginary column.. of each term.. you can just do that single piece by it self.... 2x + 3x = 5x   and 2y +(-2y) = 0  and -2 + 12 = 10  :)

so now I can rewrite our new equation

5x = 10    I can solve this one with my eyes closed  :D  (10/5 = 2 )

x =2   :P

now , since we know x  .. just plug in the known value of x into the 1st equations...  

2(2) +2y = -2

4 + 2y =-2

2y = -2-4

2y = -6

y = - 3   :) ( I had to keep my eyes open that time b/c there was a minus sign floating about and those are too easy to mess up on .. when you do.. don't worry everyone does )

so we know

x = 2  and y = -3  :)

I'll go a little faster on 2.. and I see 3 is good for you to practice on.. just ask later if you have questions on that one.

system 2

4x - 2y = -1

-4x + 4y = - 2

add them again to get rid of the x term

0x +2y = -3

y = - 3/2

plug in y

4x  - 2(-3/2) = -1

4x +3 = -1

4x = -1 - 3

4x = -4

x = -1  

they are being nice and making them easy to start out.. you try system 3

Answer:

Step-by-step explanation:

Answer:

3/2 or 1 1/2

Step-by-step explanation:

5÷3 1/3

5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide

5/1 × 3/10 because you have to multiply the first number by the reciprocal

5  and 10 cancel out so you would have 2 at the bottom

3/2 or 1 1/2

Answer:

3x + 4y = 72

Step-by-step exlanation:

Number of pizzas = x

Number of sandwich trays = y

one large pizza can feed 3 players

one sandwich tray can feed 4 players

Total players = 72

The linear equation is

3x + 4y = 72

Answer:

[tex]y = 1500(0.024)^t[/tex]

Step-by-step explanation:

Given

[tex]a = 1500km[/tex] -- initial area

[tex]b = 2.4\%[/tex] -- rate

[tex]t = time[/tex] --- (years)

Required

Represent as an exponential function

An exponential function has the form:

[tex]y = ab^t[/tex]

Where

[tex]a = initial\ value[/tex]

[tex]b = rate[/tex] and [tex]b \ne 1[/tex]

[tex]t= time[/tex]

Substitute values for a and b, we have:

[tex]y = 1500 * (2.4\%)^t[/tex]

Convert percentage to decimal

[tex]y = 1500 * (0.024)^t[/tex]

[tex]y = 1500(0.024)^t[/tex]

Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]

Answer:

75

Step-by-step explanation:

Sea level is considered 0. To find 75 feet above sea level, we add 75 to 0. This gets us 75. Since 75 is an integer, it checks out.

The required integer would be 75 which describes 75 feet above sea level.

Integers are defined as the collection of Whole Numbers and the negative values of Natural Numbers make up an integer. Fractional numbers are not included in integers. Integers are represented by the symbol Z.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Let the sea level would be considered zero.

To determine 75 feet above sea level,

We have to add 75 to 0.

⇒ 75 + 0

⇒ 75

This obtains us 75.

Since 75 is an integer.

Therefore, the required integer would be 75 which describes 75 feet above sea level.

i didnt kno i could answer my own

Step-by-step explanation:

Answer:

1.2×10¹⁰

Step-by-step explanation:

Given that,

The population of the state = 2,000,000

Average Citizen spends on housing = 6000

We need to find the total spent on housing for the state.

Total spent on housing for state = Population of State × Average Citizen

Total spent = 2,000,000 × 6,000

= 1.2×10¹⁰

Hence, the total spent on housing for the state is 1.2×10¹⁰.

Answer:

Its B

Step-by-step explanation:

since the symbol has a line underneath its shaded so A & B are left.

the symbol shows > so the point is where the line goes, for this question it goes to the right.

The required number line represents the solution to 5x ≥ 30 is shown in option B.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
According to the question, the inequality 5x ≥ 30 can be solved by dividing both sides by 5, which gives x ≥ 6. This means that any number greater than or equal to 6 is a solution to the inequality.

Looking at the number line options, we can see that only the last one correctly represents the solution to the inequality. The line starts at 6 and includes all numbers greater than or equal to 6, which matches the solution x ≥ 6.

Therefore, the correct answer is the number line shown in option B.

Answer:

675

Step-by-step explanation:

675x0.04=27

Answer:

v = 3.75 mph

Step-by-step explanation:

Constant speed motion

An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.

Expressed in a simple equation, we have:

[tex]\displaystyle v=\frac{d}{t}[/tex]

Where  

v = Speed of the object

d = Distance traveled

t = Time taken to travel d.

Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.

t=12/60 = 0.2 hours. Now compute the speed:

[tex]\displaystyle v=\frac{0.75\ mi}{0.2 \ h}[/tex]

v = 3.75 mph

Answer:

I hope this helps.

Step-by-step explanation:

Answer:

[tex]f(x) = 2x - 4 \\ f(x + 3) = 2(x + 3) - 4 \\ = 2x + 6 - 4 \\ = 2x + 2 \\ = 2(x + 1)[/tex]

Answer:

x = -15

m = -3

Step-by-step explanation:

3x + 6 = x - 24

subtract the x from both sides to make the unknown variable on only one side of the equation

2x + 6 = -24

subtract the 6 from both sides to focus on the x

2x = -30

now divide both sides by 2 to get the x by itself

x = -15

that's your answer

10 - 2m = 16

subtract the 10 from both sides to focus on the m

-2m = 6

now divide both sides by -2 to get the m by itself

m = -3

that's your answer
