Answer:

x: {-3, 5}

Step-by-step explanation:

Step 1. Find least common denominator

Step 2. Multiply missing factors on top AND bottom

Step 3. Combine like terms

Step 4. Simplify (get rid of denominator)

Step 5. Solve for x

[tex]\frac{x}{x-5} +\frac{3}{x+2} =\frac{7x}{x^2-3x-10}[/tex]            LCD = [tex]x^2-3x-10[/tex]   OR  [tex](x-5)(x+2)[/tex]

[tex]\frac{x}{x-5}(\frac{x+2}{x+2}) +\frac{3}{x+2}(\frac{x-5}{x-5}) =\frac{7x}{x^2-3x-10}[/tex]

[tex]\frac{x(x+2)}{(x-5)(x+2)} +\frac{3(x-5)}{(x+2)(x-5)} =\frac{7x}{(x-5)(x+2)}[/tex]

[tex]\frac{x(x+2)+3(x-5)}{(x-5)(x+2)} =\frac{7x}{(x-5)(x+2)}[/tex]

[tex]\frac{x^2+2x+3x-15}{(x-5)(x+2)} =\frac{7x}{(x-5)(x+2)}[/tex]

[tex]\frac{x^2+5x-15}{(x-5)(x+2)} =\frac{7x}{(x-5)(x+2)}[/tex]

[tex]x^2+5x-15=7x[/tex]

[tex]x^2-2x-15[/tex]

[tex](x-5)(x+3)[/tex]

x = -3, 5

The resulting equation of that step is the square root of  (x + 2)²  is  (x + 2).

A square root function is defined as a one-to-one function that takes a positive number as an input and returns the square root of the given input number.

From there, it was pretty easy for Theo to find the solutions

to the original equation.

If  (x + 2) = +2 , then  x = 0 .

If  (x + 2) = -2 , then  x = -4

Hence, the resulting equation of that step is the square root of  (x + 2)²  is  (x + 2).

Answer: 17160 feet

Step-by-step explanation:

We know that 5280 feet = 1 mile

So all we have to do is multiply 3 1/4 by 5280

Let's split the 3 and 1/4 up to make the multiplication easier

3×5280=15840

[tex]\frac{1}{4}[/tex]×5280=[tex]\frac{5280}{4} =1320[/tex]

Now add them together

15840+1320=17160

Step-by-step explanation:

To make a stem and leaf plot, each observed value must first be separated into its two parts:

1)The stem is the first digit or digits;

2)The leaf is the final digit of a value;

3)Each stem can consist of any number of digits; but,

4) Each leaf can have only a single digit.

Using the table at the right, Kim would have to classify the water as gaseous matter in this case.

The states of matter are the distinct form in which matter exists. There are 5 states of matter Solids; Liquids; Gaseous; Plasma; and Bose-Einstein condensate.

Kim classify the water as gaseous because she boiled all the liquid away. Hence in their evaporated state, the water now assumes a gaseous form.

The masses of solids left in the there samples were 2.025 grams, 457 mg, and 589 mg.

Matter can exist in various states. They are Solids; Liquids; Gaseous; Plasma; and Bose-Einstein condensate. (which is Man-made).

Answer:

18.8

Step-by-step explanation:

Hey there!

In order to find the solution to this question, we need to find the circumference

To find the circumference, you need to take the diameter and multiply it by 3.14 which is pi

In this case, the diameter is 6

6 x 3.14 is 18.84 so this means that the circumference of the circle, or in this case, a cookie, is 18.84

Also, it says to round to the tenth so our final answer will be 18.8

So the answer to this question is 18.8

C=18.8

The interest will the CD has earned more than the savings account after 1 year will be $49.90. Then the correct option is B.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Greg invests $2,680 in a CD paying 7.0% interest, and $3,060 in an online savings account paying 4.5% interest.

The amount of the interest on the CD will be

→ 2680 × 0.07 = $187.6

The amount of the interest by the online savings will be

→ 3060 × 0.045 = $137.7

Then the interest will the CD has earned more than the savings account after 1 year will be

→ $187.6 - $137.7 = $49.90

Answer:

the median is 15, there is no mode.

Step-by-step explanation:

to find the median- put the numbers in order from least to greatest (13,14,14,16,16,19) use a sheet of paper and cross off each number on the ends until you get to the middle. Once you have reached the middle you should have the two numbers 14, 16. Take 14 and 16, add them together and you will get 30. Divide 30 by 2 because there is two numbers for the median. You should end with 15 as your median.

to find the mode- find the number that occurs the most in the set of numbers, in this case all numbers occur the same amount of times, so therefor there is no mode.

Answer:

[tex] \sf \fbox{Option D have pair of triangles are similiar}[/tex]

Step-by-step explanation:

To prove triangles are pair we will use AAA property.

ln option A the given triangles 1 & 2 have a 36° Angle, but the remaining two angles of both the traingle are not mentioned, as long as we don't know the measure of other two angle of both the traingle we can't say that pair of triangles are similar.

Similarly In option B triangles 3 & 4 can't be pair of similar triangle

In option C triangle 5 & 6 don't have any common angle, hence it does not follows AAA property and the given pair of traingles are not similar.

In option D Two angles of each triangle are given so we can easily find the third angle of both the triangle. let's solve for the third angles of triangle 7 and 8.

in triangle 7,

All three angles of triangle 7 are 30, 60 & 90

Now in triangle 8,

All three angles of triangle 8 are 30, 60 & 90

Hence, both the triangles have same measure of all three angles we can say that triangle 7 & 8 are similar triangle.

Answer:

Step-by-step explanation:

First calculate the amount of notebooks and textbook

Cost of 2 notebooks = 2 *8.75

                                  = $ 17.5

Cost of 1 textbook = $ 74.95

Total cost = 17.5 + 74.95

                 = $ 92.45

Tax = 7% of total cost

      = 0.07 * 92.45

      = $ 6.47

Total cost = 92.45 +6.47

                 = $ 98.92

Jaleesa bought 2 notebooks for dollar 8. 75 and 1 textbook for dollar 74.95 . If the sales tax was 7[tex]{\%}[/tex],

what was the total cost of Jaleesa's purchases?

In this question we are provided with the cost of each textbook and notebook and it is given that Jaleesa bought 2 notebook and 1 textbook and the sale tax was.7% and we are asked to calculate the total cost of Jaleesa's purchases

First we will calculate the cost of two notebooks

Rate of 1 notebook = $8.75

Cost of 2 notebook = $(8.75 × 2) = $17.5

Now, we will calculate the total cost

Total cost of 2 notebook and 1 textbook = $(17.5 + 74.95) = $92.45

Sales tax was 7%

7% of $92.45

→ [tex]\dfrac{7}{100}[/tex] × 93.45

→ $6.47

Total cost = $(92.45 + 6.47) = $98.92.

Answer:

B

Step-by-step explanation:

Because 0.75 is less than 1, the bigger x is, the smaller the whole thing will get. And the 4.1 in front is the starting point on the left side of the graph. Like on an actual graph with numbers:

If x is 0, f(x) is 4.1

If x is 5, f(x) is 0.97

The graph is decreasing. This is an equation and graph for "decay"

Answer: 4 pounds > 60 ounces (D)

Step-by-step explanation:

Since there are 16 ounces in a pound, you just multiply 16 (ounces) by 4 (pounds). If you evaluate 16*4, you would get 64 ounces, so 64 is greater than 60. So the answer is D.

The expressions that can represent the total number of balloons in p packages of large balloons is 12 × p or 12p. Hence, options B and E are correct.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given statement in the question,

The number of balloons in the package = is 12

Total number of packages = p
