Answer:

21/5

Step-by-step explanation:

Answer:

Let’s assume a,b,x real. Then all we require of y is y2 is real, so y

can be real or purely imaginary, but not an arbitrary complex number.

The hard question in these is always, do we need ±

? Here the answer is yes. It’s basically asking is there one solution or two, and in this problem we have two.

Solve for y

The value of x from the triangle ΔEAD is x = 41°

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as ΔABC

Let the second triangle be represented as ΔEAD

Now , the measure of side AC = 4.8

The measure of side BA = 3.1

And , the measure of side EA = 4.8

The measure of side DA = 3.1

And , Corresponding sides of similar triangles are in the same ratio

So , the triangles ΔABC and ΔEAD are similar

Therefore , the angles will also be congruent

The measure of ∠ACB = The measure of ∠DEA = x°

The measure of ∠DEA = 180° - ( 53° + 86° )  ( angles of a triangle = 180° )

On simplifying the equation , we get

The measure of ∠DEA = 41°

Hence , the measure of x = 41° and they are similar triangles

Step-by-step explanation:

Here we will show you how to calculate 6 divided by 3/8. We will give you the answer in fraction form and in decimal form.

Here is 6 divided by 3/8 displayed mathematically in colors:

6

 ÷    

3

8

The numbers in 6 divided by 3/8 are labeled below:

6 = whole number

3 = numerator

8 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

6 x 8

3

 =    

48

3

Thus, the answer to 6 divided by 3/8 in fraction form is:

48

3

To make the answer to 6 divided by 3/8 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

48 / 3 = 16

The answer is rounded to the nearest two decimal points if necessary.

48/3 can be simplified to 16/1.

16/1 is an improper fraction and should be written as 16.

Answer:

−6x−19y−56

Step-by-step explanation:

−8(2x)+5(2x−12)+−2(5y−2)+(−3)(3y)

Multiply −8 and 2 to get −16. Multiply −3 and 3 to get −9.

−16x+5(2x−12)−2(5y−2)−9y

Use the distributive property to multiply 5 by 2x−12.

−16x+10x−60−2(5y−2)−9y

Combine −16x and 10x to get −6x.

−6x−60−2(5y−2)−9y

Use the distributive property to multiply −2 by 5y−2.

−6x−60−10y+4−9y

Add −60 and 4 to get −56.

−6x−56−10y−9y

Combine −10y and −9y to get −19y.

−6x−56−19y

Answer:

$25.50

Step-by-step explanation:

35 - 9.5 = x

25.5 = x

Answer:

Step-by-step explanation:

Let p=pop corn and x=tickets.

Because they have $9.50 on popcorn you should subtract 9.50 from 35. This gives you $25.50 dollars.

Because you know that they used the rest of the money to but tickets, they spent $25.50 on tickets

Therefore the equation should be 35-9.50=x or x=35-9.50

Answer:

? = 64°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

The third angle in the triangle on the right is

third = 180° - (84 + 36)° = 180° - 120° = 60°

Thus the third angle in the triangle on the left is

third = 90° - 60° = 30° , then

? = 180° - (86 + 30)° = 180° - 116° = 64°
