Answer:  The correct option is (A) 7\dfrac{1}{24}.

Step-by-step explanation:  We are given to perform the following indicated operation :

E=1\dfrac{2}{3}+5\dfrac{3}{8}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following rule :

a\dfrac{b}{c}=\dfrac{ac+b}{c}.

From (i), we get

E\\\\=1\dfrac{2}{3}+5\dfrac{3}{8}\\\\\\=\dfrac{5}{3}+\dfrac{43}{8}\\\\\\=\dfrac{40+129}{24}\\\\\\=\dfrac{169}{24}\\\\\\=7\dfrac{1}{24}.

Thus, the required answer is 7\dfrac{1}{24}.

Option (A) is CORRECT.

Snezhnost [94]
All so have to do is make sure to convert the negatives and positives of the second group of values since there is a subtraction symbol that you have to distribute to that section.

This would turn the expression into
3x^5 + 3x^2 - 4x^3 + x - 6 - x^3 - 4x^4 - 2x^2 + 10x

Then combine like terms and line all the values in order from greatest exponent value to least to get 
3x^5 - 4x^4 - 5x^3 + x^2 +11x - 6

Hope this helped :)

The model of a trinomial is shown.
galben [10]

The factors of the trinomial based on the information given include:

C. x – 7

E. x + 2

<h3>What is a trinomial?</h3>

It should be noted that a trinomial is an algebraic expression that has three non-zero terms. Here, the examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. Also, 2a² + 5a + 7 is a trinomial in one variables.

In this case, the algebra tile configuration has 0 tiles are in the Factor 1 spot and 0 tiles are in the Factor 2 spot. 24 tiles are in the Product spot: 1 is labeled + x squared, 7 are labeled negative x. Here, the trinomial is x² - 5x - 14.

The factors will be:

x² - 5x - 14.

x² + 2x - 7x - 14

x(x + 2) - 7(x + 2)

= (x + 2)(x - 7)

A polynomial with three terms is called a trinomial.

In conclusion, the correct options are C and E.

irina [24]

Answer: Our required probability is 0.99338.

Step-by-step explanation:

Since we have given that

n = 100

p = 0.200

So, np=100\times 0.2=20>5

So, we can apply normal approximation.

Mean = 20

Standard deviation = \sqrt{npq}=\sqrt{100\times 0.2\times 0.8}=\sqrt{16}=4=\sigma

Since z=\dfrac{\bar{X}-\mu}{\sigma}

So, Probability that fewer than 30 but a packet after testing a free sample is given by

P(X

Hence, our required probability is 0.99338.

I need an answer soon, please! Whoever answers first will get Brainliest!!! Please no troll answers!
Colt1911 [192]

Answer:

x = 8, and y = 12

Step-by-step explanation:

There are 2 variables, so you need 2 equations to form a system of equations in two variables.

The upper left triangle has all angle measures given: 100, 2x + y, 5x + y. We know that the sum of the measures of the angles of a triangle is 180.

First equation:

100 + 2x + y + 5x + y = 180

Simplify:

7x + 2y = 80     (First equation)

Now we see that the upper and lower sides are parallel, so alternate interior angles are congruent. The angles measuring 2x + y and 5x - y are alternate interior angles and are congruent.

Second equation:

2x + y = 5x - y

Simplify:

3x - 2y = 0    (Second equation)

Now we use the first equation and the second equation as a system of simultaneous equations to solve for x and y.

7x + 2y = 80

3x - 2y = 0

Solve the second equation for 2x.

3x = 2y

Now replace 2y in the first equation with 3x.

7x + 3x = 80

10x = 80

x = 8

Replace x with 8 in the second equation.

3(8) - 2x = 0

24 = 2x

x = 12

Answer: x = 8, and y = 12
