<h3>How to find the volume of a cube?</h3>

The formula for volume of a cube is given by;

V = l³

where;

V is volume

l is side length of cube

Now, we are given;

Volume of cube = 64 in³

Thus;

l³ = 64

l = ∛64

l = 4 inches

Thus, we conclude that the length of the new room is 4 inches.

MATH RIDDLE! HELP!!!

madreJ [45]

The method for working out how much they each paid is incorrect, lets look at it from a different perspective.

The 3 guys paid him $30, now he gives back $5 to the guys.

So there is $25 with the owner and $5 with the bell boy.

Now the bell boy keeps $2 and gives back $3, $1 to each of the guys.

So there is $25 with the owner, $2 with the bell boy and $3 with the guys.

Now indeed the guys paid $30 - $3 which is $27 dollars, but we can see that that is now split between the owner and the bell boy as $25 + $2 = $27 dollars.

What is 5/12 Plus 5/12?

mestny [16]

$\sf\dfrac{5}{12}+\dfrac{5}{12}$

Since we already have like denominators, just add the numerators and keep the denominator.

$\sf\dfrac{5+5}{12}\rightarrow\dfrac{10}{12}$

Simplify:

$\boxed{\sf\dfrac{5}{6}}$

Choose a system of equations with the same solution as the following system:

Lina20 [59]

Answer:

Option A.

Step-by-step explanation:

We are given 6x+2y =-6 ......(1) and 3x-4y=-18 .....(2)

Solving equations (1) and (2) we get

12x+3x =-30, ⇒x= -2 and from equation (1), 2y= -6-6(-2) =6, ⇒ y=3

Therefore, the solution for the given set of equations is x= -2 and y=3

A) Solving the equations 8x+4y = -4 ....... (3)and 17x+2y =-28, we get

8x -34x = -4 -(-56) =52, ⇒-26x =52, ⇒x=-2 and from equation )(3), we get -16+4y =-4, ⇒ y=3

Therefore, the solution x=-2 and y =3 match with the original solution.

B)Solving the equations 12x + 4y = 12 ....... (4)and 21x + 2y = −36, we get

12x -42x = 12 -(-72) =84, ⇒-30x =84, ⇒x=-84/30.

Therefore, the solution x=-84/30 does not match with the original solution.

C) Solving the equations 6x + 8y = −36 ....... (4) and 15x + 6y = −60, we get 18x -60x = -108 -(-240) =132, ⇒-42x =132, ⇒x=-132/42

Therefore, the solution x=--3 do not match with the original solution.

D) Solving the equations 6x + y = 15 ....... (5) and 15x − y = −9, we get 6x +15x = 6, ⇒21x =6, ⇒x=2/7

Therefore, the solution x=2/7 do not match with the original solution.

Therefore, option A) will have the same solution. (Answer)

Is 3/x+4/y=2 linear or non-linear

Eduardwww [97]

The given equation is non-linear.

Solution:

Given expression is $\frac{3}{x} +\frac{4}{y} =2$ .

To find the equation is linear or non-linear.

Linear equation is a straight line which is in the form ax + by + c = 0.

Otherwise it is non-linear equation.

⇒ $\frac{3}{x} +\frac{4}{y} =2$

Do cross multiply for the fractions to make the denominators same.

⇒ $\frac{3y}{yx} +\frac{4x}{yx} =2$

⇒ $\frac{3y+4x}{yx} =2$

Do cross multiplication.

⇒ $3y+4x=2yx$

⇒ $4x+3y-2yx=0$

Here, there is no constant term.

So, the equation is not a straight line.

Hence, the given equation is non-linear.
