Answer: Infinitely many solutions

Step-by-step explanation:

Let's take the first equation.

3y + 6x = 12

Now take common,

3( y + 2x ) = 12

So, y + 2x = 4

Lets take 2nd equation

4y + 8x = 16

Take common,

4(y + 2x) = 16

So, y + 2x = 4.

Two lines with same equation have infinitely many solutions. These two equations are the same so there are infinitely many solutions.

approximately 2 wax cubes

Step-by-step explanation:

number of wax cubes needed = volume of square pyramid / volume of cube

Volume of a pyramid = 1/3 x ( base area x height)

base area = length²

6² = 36

volume = 1/3 x (36 x 9) = 108

volume of a cube = length³

4³ = 64cm³

108/64 = 1.69

hoa [83]

Answer:

PA GEN SOLISYON → NO SOLUTION

Step-by-step explanation:

10x - 2x - 8 = 8x - 16 + 6 >> 8x - 8 = 8x - 10

8x - 8 = 8x - 10

Using the following image, solve for SR. Look at the image closely.

iren [92.7K]

Step-by-step explanation:

I assume

SR = 2x + 23

RQ = x + 21

if that is true, then the situation is completely simple :

14 = (2x + 23) + (x + 21) = 3x + 44

3x = -30

x = -10

SR = 2×-10 + 23 = -20 + 23 = 3

RQ = -10 + 21 = 11

A cake recipe calls for 2 1/2 cups of flour. If Mrs. Hizon will prepare for 4 2/3 servings of the recipe, how much flour will sh

Rasek [7]

let x be the flour

now

or,(21/2)+x=42/3

or,(21+2x)/2=42/3

or, 3(21+2x)=42×2

or, 63+6x=84

or,6x=84-63

or, 6x =21

or, x=21/6

thus she need 21/6 cups of flour
