Answer:

The answer is that in my case y (the smaller number) is 2 and x (the bigger number) is 6

Step-by-step explanation:

The equations are x=3*y and y+4=x. This makes y=2 and x=6.

8 - 2 = 6

-2m - 12n + 6

-5x + 3y + 9x + 7

-5x + 9x = 4x

3y = 3y

7 = 7

4x + 3y = 7

-2y + 4x - 3y + 6x - 12 for x = 2 and y = -4

Substitute :

The sum of the interior angle measures of a convex octagon is 1080. the correct option is A.

An octagon is an 8-gon, or polygon with eight sides, in geometry. The Schläfli symbol for a regular octagon is 8, and it can also be built as a nearly regular truncated square.

The interior angle will be calculated as,

Angle = (n - 2) x 180

Angle = ( 8 - 2 ) x 180

Angle = 1080

Therefore, the sum of the interior angle measures of a convex octagon is 1080. the correct option is A.

Answer:

n+5

Step-by-step explanation:

Answer:

n + 5 or 5 + n

Step-by-step explanation:

add 5 to n, tanya's current age, to find how old she'll be in 5 years.

since the variable n is not defined, the answer cannot be simplified further than n + 5.

if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.

Answer: X = -4

Step-by-step explanation:

90 - 5x + 62 -2x = 180

152 - 7x = 180

-7x = 28

x = -4

Check your answer by pluging in the vaule of x

90 - 5(-4)

90 + 20 = 110

62 - 2(-4)

62 + 8 = 70

110 + 70 = 180

Checks out.

Answer: 110 degrees and 70 degrees

Step-by-step explanation:

These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180

Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180

Subtract 152 from both sides of the equation.

-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70

We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

Step-by-step explanation:

Area of this shape = 614²

Length of side of the first square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the first square = 100²

Length of the side of the second square = 10

It's area :

[tex] = \tt \: side\times side[/tex]

[tex] =\tt 10 \times 10[/tex]

[tex] = \tt{100}^{2} [/tex]

Thus, the area of the second square = 100²

Length of the side of the third square = 10

It's area :

[tex] =\tt side \times side[/tex]

[tex] = \tt 10 \times 10[/tex]

[tex] = \tt {100}^{2} [/tex]

Thus, the area of the third square = 100²

(pi value = 3.14)

Radius of the first semicircle = 10 cm

It's area :

[tex] = \tt \: \frac{\pi {r}^{2} }{2} [/tex]

[tex] = \tt \frac{3.14 \times 10 \times 10}{2} [/tex]

[tex] = \tt\frac{3.14 \times 100}{2} [/tex]

[tex] =\tt \frac{314}{2} [/tex]

[tex] =\tt {157}^{2} [/tex]

Thus, the area of the first semicircle = 157²

Area of the second semi circle :

= area of the first semicircle

= 157²

Thus, the area of the second semicircle = 157²

Total area of the figure :

= Area of the 3 squares + Area of the two semi circles

[tex] =\tt 100 + 100 + 100 + 157 + 157[/tex]

[tex] = \tt300 + 314[/tex]

[tex] = \tt {614}^{2} [/tex]

Therefore, the total area of the figure = 614²

Step-by-step explanation:

======================================

Work Shown:

c = price of coat before discount

0.33c = discount = amount you save

c - 0.33c = original price minus discount = final price

c - 0.33c = 1c - 0.33c = (1-0.33)c = 0.67c = final price

In short, c - 0.33c = 0.67c

They are two ways of expressing the same thing.

You can think of it like saying 100% - 33% = 67%

If you save 33%, then you still have to pay the remaining 67% of the original cost.

-------------

Example:

Let's say the coat is $100 before the discount

c = 100

0.33*c = 0.33*100 = 33 dollars is how much you save

c - 0.33c = 100 - 33 = 67 dollars is the final price

0.67c = 0.67*100 = 67 matches with the previous figure above

Answer:

  100% is an integer multiple of 10%

Step-by-step explanation:

100% is not an integer multiple of 30%, so it is difficult to use 30% directly to determine the value of 100%. Dividing 30% by 3 to get 10% then gives you a value that can be multiplied by 10 to find 100%.

Explanation:

Notice how EC = 5 doubles to BC = 5+5 = 10

So the larger quadrilateral (ABCD) has side lengths that are exactly twice as long compared to the smaller quadrilateral's sides. We can say the scale factor is 2.

This must mean that side FG = 4 doubles to 4*2 = 8, which is the length of side AD. So that's how we get y = 8.

-----------------------------------

Extra info:

Length of AD, y = 8

Two quadrilaterals are similar if their corresponding angles are equal and also their corresponding sides must be proportional.

Given,

EC = 5

FG = 4

BE = 5

AD = y

ABCD ~ FECG,

then ratio of the corresponding sides will be equal.

BC/AD = EC/FG

(BE + EC)/AD = EC/FG

(5 + 5)/y = 5/4

10/y = 5/4

5y = 40

y = 40/5

y = 8.

Hence, 8 is value of y that is length of AD.
