Question isnt well formatted :

Answer:

1 : 6

Step-by-step explanation:

Given the question :

3x = 1/2y

3x = y/2

Multiply both sides by 2

3x * 2 = y/2 * 2

6x = y

This can be interpreted as :

y = 6 times the value of x

x = y/6

x : y

1 : 6

-6x - 7 is greater than or equal to - 19. Please guide me through the steps of this... I will give brainliest

3241004551 [841]

Answer:

x ≤ 2

Step-by-step explanation:

-6x - 7 ≥ -19

Add 7 to both sides: -6x ≥ -12

Divide both sides by 6: -x ≥ -2

Divide both sides by -1: x ≤ 2

When you divide by a negative, you have to switch the sign around (hence why I chose to do this in separate steps, so it's clearer)

X=y x+2y =3 Solve using substitution

Zielflug [23.3K]

Answer:

Therefore the Final Solution is

x = 1 and y = 1

Step-by-step explanation:

Given:

$x=y$ ...............Equation ( 1 )

$x+2y=3$ ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Equating Equation ( 1 ) in Equation ( 2 ) we get

$y+2y=3\\\\3y=3\\\\y=\frac{3}{3} \\\\\therefore y =1$

Now Substituting y = 1 in Equation ( 1 ) we get

$x =1\\\\\therefore x=1$

Therefore the Final Solution is

x = 1 and y = 1

What equation represents the model shown below?

g100num [7]

Given:

The algebra tiles of an equation.

To find:

The equation represented by the given model.

Solution:

On the left side of the model we have 4 tiles of (-x) and 3 tiles of (-1). So,

$LHS=(-x)+(-x)+(-x)+(-x)+(-1)+(-1)+(-1)$

$LHS=-4x+(-3)$

$LHS=-4x-3$

On the right side of the model we have 8 tiles of (-1). So,

$RHS=(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)+(-1)$

$RHS=-8$

Now, equate the LHS and RHS to get the equation.

$-4x-3=-8$

Therefore, the equation for the given model is $-4x-3=-8$ .
