Answer:

(2) is the correct answer

Step-by-step explanation:

if you multiply the given equation by 3 you get answer (2):

3(4x - 3y) = 3(12)

12x - 9y = 36

Answer:

(2) 12x-9y=36

Step-by-step explanation:

4x-3y=12  (×3)

12x-9y=36

Answer:4 gallons of water ... 30 plants

x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30

180 = 30 * x    /30

x = 180 / 30

x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.

Answer:

-8

Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.

how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.

Answer:

angle ADC is shown as a 90 degree angle

90 - 22 = 68

so I would go with 68 degrees

5x10^-10 is the answer

Answer:

12.5 pie , 39.25 using pie=3.14, and 39.28 to be exact

Step-by-step explanation:

BTW n=pie

10in= Diameter

5in=Radius

Area=n5^2

= 25n/2

=12.5n

12.5 times 3.14= 39.25

22/7 times 12.5= 39.2857143

It's A I hope that helps

Step-by-step explanation:

Answer:

Length=10 feet

Width=6 feet

Step-by-step explanation:

Let width (W) of the garden is x feet

Then Length=L=4+x feet

Perimeter=P=2(W + L)

P=2(x+x+4)

32=4x+8

4x=32-8

x=24/4=6 feet

W=6 feet

L=10 feet

Answer:

p=-17/9 or p=-1.8889

Step-by-step explanation:

-9p-17=10

add 17 to each side

-9p-17+17=10+17

-9p=17

divide both sides by -9

-9p/-9=17/-9

p=-17/9

or p=-1.8889

Solution of equation - 9p - 17 = 10 is p = -3.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x – 5 = 16 is an equation.

Given equation

- 9p - 17 = 10

Add 17 to both sides

- 9p - 17 + 17 = 10 + 17

Adding the numbers

- 9p = 10 + 17

Adding the numbers

- 9p = 27

Divide both sides by - 9

-9p/ - 9 = 27/ - 9

Cancel terms that are in both the numerator and denominator

p = 27/ - 9

Divide the numbers

p = -3

Hence, p = -3 is the solution for equation - 9p - 17 = 10

Answer:

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]

[tex] \frac{10}{x} = \frac{16}{144} [/tex]

Cross multiply

[tex] 10*144 = 16*x [/tex]

[tex] 1440 = 16x [/tex]

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²

0

Step-by-step explanation:

the equation on finding slope is y2 - y1/x2 - x1

so it is...

6 - 6 = 0

6 - -5 = 11

0/11 but that doesnt work so I believe the slope is zero because the denominator is not the one being a 0

hope I helped ;)

Answer: its a zero slope

Answer:

8

Step-by-step explanation:

8*4 is 32 8*9 is 72

so, it is 8

since it is distributive property 8(4+9)

Answer:

8

Step-by-step explanation:

1) simplify the equation

32+72=104

104=4x+9x (distibute the "x")

104=13x

x=8

hence the "blank" is 8

Answer:

B. (1, 0)

Step-by-step explanation:

9514 1404 393

Answer:

  B.  (1, 0)

Step-by-step explanation:

You can count grid squares on the graph to find the point that is 4 of the 8 units horizontally between the points, and 2 of the 4 units vertically between the points. That will be ...

  C +(4, 2) = D -(4, 2) = (1, 0)

__

Or, you can use the midpoint formula:

  M = (C +D)/2

  M = ((-3, -2) +(5, 2))/2 = (-3+5, -2+2)/2 = (2, 0)/2

  M = (1, 0)

The midpoint is (1, 0).

Answer: -6<x<5

Step-by-step explanation:

Given

Length is 3 m more than three times the width

Suppose width is x

So, the length is 3x+3

The area of a rectangle is  [tex]length\times width[/tex]

Area= [tex](3x+3)x<90[/tex]

[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]
