Answer: -6 = x

Step-by-step explanation: Start by distributing through the parentheses

on each side of the equation to get 5x - 40 = 7x - 28.

Now move your x's to the right and

numbers to the right and you get -12 = 2x.

Divide both sides by 2 and -6 = x

Answer:

Hi You

5(x -8) = 7(x -4)

5x - 40 = 7x - 28

5x - 40 + 40 = 7x - 28 + 40

5x = 7x + 12

5x -7x = 7x - 7x +12

-2x = 12

-2x/-2 = 12/-2

x = -6

Step-by-step explanation:

proving my answer.

5(-6 - 8)

(5×-6)-(5×8)

= -30-40

= -70

7(-6-4)

(7×-6) - (7×4)

-42 - 28

= -70

hope that will help you.

You are filling paper cones with popcorn for a party.

Sunny_sXe [5.5K]

Answer:

The amount of popcorn needed to fill the paper cone is $V=1,005\ cm^{3}$

Step-by-step explanation:

we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

In this problem we have

$r=8\ cm$

$h=15\ cm$

$\pi =3.14$

substitute

$V=\frac{1}{3}(3.14)(8)^{2}(15)$

$V=1,005\ cm^{3}$

Y=3x-8 in function notation

julia-pushkina [17]

To write it in function notation you'll convert it into a function, substituting y by f(x):

y = 3x - 8 = f(x) = 3x - 8

Hope it helped,

What is the result of adding these two equations? \begin{aligned} 2x+3y &= -5 \\\\ 5x-y &= -12 \end{aligned} 2x+3y 5x−y

EleoNora [17]

Answer:

$7x+2y = -17$

Step-by-step explanation:

We have the following equations:

$2x+3y = -5$

$5x-y = -12$

If we want to add these equations, we just need to add x-terms, y-terms and independent terms.

$(2x+5x)+(3y-y) = -5-12$

$7x+2y = -17$

I hope it helps you!
