Answer:

x=20, y=100

Step-by-step explanation:

3x+2x=7x-40

5x=7x-40

2x=40

x=20

7x-40=y

140-40=y

100=y

y=100

According to the exterior angle theorem, the two remote interior angles are equal to the exterior angle. This is why we set 3x+2x equal to 7x-40.

According to the vertical angles theorem, two angles that are opposite and formed by two intersecting straight lines are equal. This is why we set 7x-40 equal to y.

Because we already knew that x was 20, we could put it into our equation. (7*20)-40=y.

Answer:

incenter hope it helps

Step-by-step explanation:

The point of concurrency that always lies on the interior of a triangle is to be considered as the incenter.

Here the incenter refer to the concurrency point of the angle bisectors with respect to all of the interior angle.

Here, the point where three angle bisectors of the angles of the triangle should be met out is called as the incenter.

Also, the incenter should always be lies within the triangle.

Therefore, the option c is correct.

Step-by-step explanation:

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply

Answer:

Ground shaking is the primary cause of earthquake damage to man-made structures. Many factors influence the strength of earthquake shaking at a site including the earthquake's magnitude, the site's proximity to the fault, the local geology, and the soil type.

The places on the planet where one plate meets another are the most prone to earthquakes. The specific surfaces where parcels of earth slip past each other are called faults. As plates move, pressure builds up across their boundaries, while friction holds them in place

Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates. The Ring of Fire is the most seismically and volcanically active zone in the world.

False

We can simplify the expression to be sure: 100 * 0.15 = 15

Answer:

No

Step-by-step explanation:

You can do this in two ways-

You can multiply 0.15 and 100, and you will get 15.

-OR-

You can move the decimal points two places to the right since 100 has two zeros. (You could move it to the right three if it were 1000 because it has three 0s)

The angles of both figures are listed in the same order. The first angle of the first one is congruent to the first angle of the second, and the second angle of the first one is congruent to the second angle of the second figure, and so on.

Step-by-step explanation:

You have a repeated 'F' in naming the first figure, so I think you made an error. But the rule in my answer is true and you can apply it.

Answer:

Store C

Step-by-step explanation:

store a is selling 10 pencils for $2.50

$2.50 divided by 10 is 25 cents

so the price for store a is 25 cents per pencil

store b is selling 50 pencils for $6.00

$6.00 divided by 50 is 12 cents

so the price for store b is 12 cents per pencil

store c is selling 100 pencils for $8.25

$8.25 divided by 100 is 8.25 cents

obviously you can't give someone .25 cents so round it down to 8

so the price for store c is 8 cents per pencil

store d is selling 250 pencils for $21.25

$21.25 divided by 250 is 8.5 cents

which rounds up to 9 cents per pencil

Store c has the lowest price for one pencil
