I have having a problem with this equation 3(-2-3x) = -9x-4

inn [45]

Answer:

3(-2-3x) = 9x-4

-6-9x = 9x-4

-6+6-9x = 9x-4+6

-9x = 9x+2

-9x-9x = 9x-9x+2

-18x = 2

-18x÷(-18) = 2÷(-18)

x = -(1/9)

Thank you

Answer:

Step-by-step explanation:

$y=-x^{2} -5x-6$

$y=-(x^2+5x+6)$

$y=-(x+3)(x+2)$

Set each factors equal to zero.

$(x+3)=0 , x=-3$

$x+2=0 , x=-2$

The x-int is

Given:

Kelly purchased 5 containers of ice cream for a party.

Each container holds 8 cups of ice cream.

Her brother ate 2 cups of ice cream.

One serving of ice cream = 2/3 of a cup.

To find:

Number of servings of ice cream will be left for the party?

Solution:

We have,

1 container = 8 cups of ice cream

5 containers = 5×8 = 40 cups of ice cream

Her brother ate 2 cups of ice cream. So, remaining cups of ice cream is

$40-2=38$ cups

Now,

$\dfrac{2}{3}$ of a cup = 1 serving

1 cup = $\dfrac{3}{2}$ serving

38 cup = $38\times \dfrac{3}{2}$ serving

= $19\times 3$ serving

= 57 serving

Therefore, 57 servings of ice cream will be left for the party.
