Answer:

x = 27

Step-by-step explanation:

2/3 x - 1/9 x + 5 = 20           Subtract 5 from both sides

2/3 x - 1/9 x = 15                  Change 2/3 to x/9

3*2/3*3 - 1/9 x = 15

6/9 x - 1/9 x = 15

5/9 x = 15                            Multiply both sides by 9

5x / 9 * 9 = 15 * 9

5x = 135                              Divide by 5

x = 27

Answer:

27 if variable is near the fraction,

-1/129 if variable is in the denominator and not numerator

Step-by-step explanation:

make 2/3 have the same denominator as -1/9

2/3*3/3=6/9

6/9x-1/9x=5/9

5/9x+5 = 20

20-5 = 15

5/9x = 15

15/(5/9x) -> x= -1/129

if you mean the whole equation has the variable x and no the denominator then it is equal to 27

Answer:

  • April
  • She did not pack enough layers of centimeter cubes
  • 240 cubic centimeters

Step-by-step explanation:

Dimensions of the prism is 5x8x6

April made a mistake, she packed 4 layers of unit cubes instead of 5 layers

<u>Correct  volume of the prism is:</u>

  • 5*8*6 = 240 cm³

<u>Correct answer choices:</u>

  • April
  • She did not pack enough layers of centimeter cubes
  • 240 cubic centimeters

Qaudriladrial ABCD had cordinates A (3, 5) B(5, 2) C(8, 4) D(6, 7) qaudriladrial ABCD is a what?
Lorico [155]

The quadrilateral is a square

<h3>What are quadrilaterals?</h3>

Quadrilaterals are polygons, that have four sides and four corners

The coordinates are given as:

  • A = (3, 5)
  • B = (5, 2)
  • C = (8, 4)
  • D = (6, 7)

Start by calculating the adjacent side lengths using:

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

So, we have:

AB = \sqrt{(3- 5)^2 + (5- 2)^2}

AB = \sqrt{13}

BC = \sqrt{(8- 5)^2 + (4- 2)^2}

BC = \sqrt{13}

The side lengths are equal.

Hence, the quadrilateral is a square

A 30°–60°–90° triangle has a shorter leg with a length of 3 units.
Lena [83]
The hypotenuse is 6. 30-60-90 triangles have a ration of x, x\sqrt{3}, and 2x, respectively. So since you have the value for the 30º side, then you just double it to get the hypotenuse's value.

Candice is making some party bags for her birthday party she has 96 stickers and 80 boxes of cookies she wants each party bags t
Irina-Kira [14]

the greatest common factor 80 and 96 is 16. And so 16 party bags she can make .

<u>Step-by-step explanation:</u>

Here we have , Candice is making some party bags for her birthday party she has 96 stickers and 80 boxes of cookies she wants each party bags to be the same and she wants to use all of the stickers and cookie  . we need to find how many party bags she can make . Let's find out:

Let's calculate GCF of 96 & 80 as :

Prime factors of 96 are :

⇒ 2^5(3)^1

Prime factors of 80 are :

⇒ 2^4(5)^1

Therefore , GCF is common factor of Prime factors of 96 and Prime factors of 80 i.e. 2^4 = 16 .

We found the factors and prime factorization of 80 and 96. The biggest common factor number is the GCF number.  So the greatest common factor 80 and 96 is 16.
