Step-by-step explanation:

Step 1: Define Systems

y = 4x + 2

6x + 2y = 8

Step 2: Solve for x

Substitution

Substitute in y:                                                                                                  6x + 2(4x + 2) = 8Factor GCF:                                                                                                       2[3x + (4x + 2)] = 8[Division Property of Equality] Divide 2 on both sides:                                  3x + 4x + 2 = 4Combine like terms [Addition]:                                                                        7x + 2 = 4[Subtraction Property of Equality] Subtract 2 on both sides:                        7x = 2[Division Property of Equality] Divide 7 on both sides:                                  x = 2/7

Step 3: Solve for y

Substitute in x [Original equation]:                                                                  y = 4(2/7) + 2Multiply:                                                                                                             y = 8/7 + 2Add:                                                                                                                   y = 22/7

Step 4: Evaluate

Substitute in variables:                                                                                     2/7 + 22/7Add:                                                                                                                   24/7

The measure of the triangle is the sum of 3 interior angles of the triangle. This is always 180 degrees, as a triangle has 3 sides and 3 angles.

The measure of the three sides of the triangle can help in finding out the angles and similarly the three angles can help to find the length. If we consider two sides and then measure the angle then the triangle can't be solved.

please help find the perimeter

Answers

Answer:

Perimeter of the given figure = 28 units

Step-by-step explanation:

Perimeter of the given figure = Length of AB + Length of BC + Length of CD + Length of DE + Length of EF + Length of FG + Length of GH + Length of AH

Length of AB = 4.5 units

Length of BC = 2 units

Length of CD = 2 units

Length of DE = 4 units

Length of EF = 5.5 units

Length of FG = 1.5 units

Length of HG = 1 units

Length of AH = 7.5 units

Perimeter of ABCDEFGH = 4.5 + 2 + 2 + 4 + 5.5 + 1.5 + 1 + 7.5

                                          = 28 units

How do I solve 1 1/3 × 2 2/4 in steps?​

Answers

Answer:

3 1/3

Step-by-Step

first step is too make a an improper fraction, 1 1/3 equals 4/3 and 2 2/4 equals 10/4. next your gonna multiply 4/3 and 10/4, 4x10=40,3x4 equals 12, so it would be 40/12. but its improper, we need to reduce it. the lowest number that can go in both numbers is 4. 40 divided by 4 =10. 12 divided by 4=3. 12/3= 3 1/3

Answer:

10/3

Step-by-step explanation:

That's 1 1/3 times 2 1/2.

Converting these into improper fractions, we get 4/3 times 5/2.

Multiplying (4/3) by (5/2), we get 20/6, or, after reduction, 10/3

Which of the following are accurate assessments of trends displayed in this graph?
I. Sales of teddy bears decreased by about 2.9% between September and October.
II. The change in sales of rabbits is roughly equal to the change in sales of all toys.
III. Roughly 24.1% fewer horses were sold in October than in September.

a. I and II
b. II only
c. I and III
d. III only

Answers

Answer:

✅ D. III only

got it right on the test⬇️

The correct statement is

Roughly 24.1% fewer horses were sold in October than in September.

What is Data?

Data refers to any information, regardless of how it is presented or represented. A data can be a numeric expression, a piece of text like a name or address, or it can be a number.

We have,

                       September         October      Trend

Teddy bears         346                   308       -10.98%

Rabbits                  297                    260       -12.46%    

Cats                       199                     285        +43.22%

Horses                  245                     186        -24.08%

Others                  225                     275         +22.22%

Total                     1,312                    1,314         +0.15

Now, Sales of teddy bears decreased by about 2.9% between September and October.

That reduced by around 11%, thus it is untrue.

II. The change in sales of rabbits is roughly equal to the change in sales of all toys.

It is untrue because variations in the sales of rabbits do not correspond to variations in the sales of all toys.

III. Roughly 24.1% fewer horses were sold in October than in September.

Yes, this is correct.

Answer:

This is the math riddle for pi..

Step-by-step explanation:

They mean by this question,  What do you get if you divide the circumference of a pumpkin pie by its diameter?

Pi is the ratio of circumference and the diameter.  and people want to understand why pi =3.14. ... very long explanation. This will be college level to understand these math.

We don’t really need the diagram at this stage of course.

The internal angle is  180o−360o / 24=180o−15o =1 65o . Half of this is  82.5o . The perimeter is now  24x  so we have:

24 x /h  = 24 / tan(82.5o) Rather remarkably:

So tan(82.5o) =√+2 + √+3+√+4+√+6

24 x / h = 24    / ( √+2 + √+3+√+4+√+6 ≈3 .1596599421

Answer the following questions using 125 words or more:
1. Write about the similarity of the original comic to the enlargement. How similar are they and how can you tell? What
would cause differences in the two pictures? If you drew another comic using a grid, is there anything you would do
differently?
2. What would happen if you reduced the comic's size rather than enlarged it? Would the process be the same? What
would you do differently?

Answers

The way in which the original comic would be similar to the enlargement is that they have the same proportion.

How is the original comic similar to the enlargement?

Based on the fact that when a comic is enlarged, the original and enlargement would remain the same and the only difference would be a larger size.

Hence, we can see that because they have the same proportion, each individual pixel in the original is more visible and the enlargement displays the image in a small number of large pixels.

The use of a grid would likely reduce the effect of pixelation and if there is a reduction in the size of the comic, there would be the same effect, only that it would be smaller, but have the same proportion.
