3x + 5y = -2
3x - 2y = - 16

Answers

Answer 1
y= -6 because we eliminated 3x, subtracted 5-2 and -2-16. that gave us 3y=-18. divide by 3 on both sides.

Mr.Jones has 160 animals on his farm.of these animals,20% are cows,30% are goats,10% are horses, and the rest are chickens.

Answers

Answer:

There are 64 chickens

Step-by-step explanation:

60% of the animals were not chickens so I found 60% of 160 which is 96, and then I subtracted 96 from 160 and got 64

Please mark brainlest for my overcomplicated description of math

Answer:

16 horses

32 cows

48 goats

64 chickens

Step-by-step explanation:

total animals = 160

⇒ 10% of animals = 160/10 = 16

⇒ 20% = 16 x 2 = 32

⇒ 30% = 16 x 3 = 48

16 horses

32 cows

48 goats

chickens = 160 - 16 - 32 - 48 = 64

(02.02)A rotation is shown in the drawing:

A green dart-shaped figure is shown, labeled Figure X. A curved dotted line shows the rotation around to the left to create a blue dart-shaped figure labeled Figure X prime. The new image is directly to the right of the original.

Which statement best describes the rotation?

A. Clockwise 90-degree rotation
B. Clockwise 270-degree rotation
C. Counterclockwise 90-degree rotation
D .Counterclockwise 270-degree rotation

Answers

Answer:

B. Clockwise 270-degree rotation

Answer:

B) Clockwise 270-degree rotation

Step-by-step explanation:

Clockwise motion is in the same direction as a clock's hands: from the top to the right, then down and then to the left, and back up to the top. The opposite motion is counterclockwise.

From inspection of the diagram, we can see that the curved dotted line (which shows the direction of motion) is suggesting a clockwise motion.

The picture represents a hippo pool surrounded by a park.
The two pentagons are similar with AB = 3 CD and the area
of the park is 2,700sq.m Find the area of the pool?



Answers

Given that the two pentagons are similar figures, the area of the pool = 675 sq. m..

What is the Area of Similar Figures?

If two figures are similar to each other, then, the ratio of the square of their corresponding sides equals the ratio of their areas.

We are given that the pool and the park are similar to each other. The diagram given is missing, however, here's how to find the area of the pool:

If x is a side of the pool and y is the corresponding side length of the park, therefore:

area of pool/area of park = x²/y².

Plug in the values given, cross multiply and find the area of the pool.

For example, if 3 is a side of the pool = x

6 is corresponding side of the park = y

Area of park = 2,700 sq. m

Thus:

Area of pool/2,700 = 3²/6²

Area of pool/2,700 = 9/36

Area of pool = (9 × 2,700)/36

Area of pool = 675 sq. m.

If 4 lattes cost 15 dollars how much would 6 caffe lattes cost?

PLEASE HELP

Answers

Answer:

The lattes would cost about 22.50

Step-by-step explanation:

In order to figure out how much 6 lattes cost we need to know how much 1 is.

So you take 15 divided by 4 which gets you 3.75

Then you take 3.75 and times it by 6. Getting you the answer of 22.50

Answer:

$22.5

Step-by-step explanation:

It would be 22.5$ because if lattes cost 15$ then we need to find the cost of 1.

To do this by we divide 15 by 4.

     3.75

4{15}

 -0

___

  15

- 12

--------

    3 so because there is 3 left of 4 is is .75 because it couldn't make it to 4

so since 1 latte cost 3.75$ we times 3.75 by 6 latte.

Here are 3.75 times numbers 1-6.

3.75 x 3=11.25

3.75 x 4=15

3.75 x 5=18.75

3.75 x 6=22.5 and there's your answer,you get 6 lattes for 22.5$ or 22$ and 50 cents.

Hope it helps have a great day:)

A.
She used a compass centered at P with a radius set equal to PQ.
B.
She used a compass centered at O with a radius set equal to PO.
C.
She used a compass centered at Q with a radius set equal to PO.
D.

Answers

ANSWER: A

I hope this helps

Answer:

D) she used a compass at P with a radius set equal to 3/4(PQ)

Step-by-step explanation:

Step 1

She used a compass at P with a radius set equal to 3/4PQ .

Step 2

Since if ∆MNP is equilateral triangle so, PM=PN=MN

Since O is center then PO=OQ

And let R is the mid point of MN.

So, R is also mid point of OQ.

Hence, she used a compass at P with a radius set equal to 3/4(PQ)

Create a linear equation for line AB and line CD

Find slope using slope formula [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

then use point-slope form of linear equation [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points on the line)

Line AB

[tex]m=\dfrac{-16+1}{-8+20}=-\dfrac54[/tex]

[tex]\implies y+1=-\dfrac54(x+20)\\\\\implies y=-\dfrac54x-26[/tex]

Line CD

[tex]m=\dfrac{0+11}{-19+9}=-\dfrac{11}{10}[/tex]

[tex]\implies y+11=-\dfrac{11}{10}(x+9)\\\\\implies y=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]

To find the point of intersection, equate the equations and solve for x::

AB = CD

[tex]\implies -\dfrac54x-26=-\dfrac{11}{10}x-\dfrac{209}{10}[/tex]

[tex]\implies -\dfrac{3}{20}x=\dfrac{51}{10}[/tex]

[tex]\implies x=-34[/tex]

Substitute found value of x into one of the equations and solve for y:

[tex]y=-\dfrac54(-34)-26=\dfrac{33}{2}[/tex]

Therefore, point of intersection is  [tex]\left(-34, \dfrac{33}{2}\right)[/tex]
