Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12

Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

Given

3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side

3x - 5x + 25 = 2x + 5

- 2x + 25 = 2x + 5 ( subtract 2x from both sides )

- 4x + 25 = 5 ( subtract 25 from both sides )

- 4x = - 20 ( divide both sides by - 4 )

x = 5

What is the slope of the line?​

Answers

Answer:

The slope is : -2/2

Step-by-step explanation:

To find the slope, start on the y-axis. -2 passes through the line on the y-axis so start there. Go up 2 unites, which will bring you to the origin. Now you need to reach -2 on the x-axis. Go left two units, which gives you 2/2. It's rise over run. It's -2 because you went left two units not right. When you go left, or down it'll be negative.

2 = rise

/

-2 = run

(x₁,y₁) = (-2,0)

(x₂,y₂) = (0,-2)

m = (y₂ - y₁)/(x₂ - x₁)

m = (-2 - 0)/(0 - (-2))

m = -2/2

m = -1

Option C

Step-by-step explanation:

Given inequality is,

-3(2x - 4) ≤ 7(3 - x)

Solve the given inequality further,

-6x + 12 ≤ 21 - 7x

(-6x + 12) + 7x ≤ (21 - 7x) + 7x

x + 12 ≤ 21

(x + 12) - 12 ≤ 21 - 12

x ≤ 9 Or {x real | x ≤ 9}

Therefore, Option C will be the correct option.

Answers

Answer:

$0.60

Step-by-step explanation:

Given that:

The ratio of number of cookies to the cost of cookies as:

Number of cookies : Cost of cookies = 15 : 9

It means, we get 15[tex]x[/tex] number of cookies when we pay $9[tex]x[/tex].

To find:

An equivalent ratio to represent the cost of 1 cookie.

Solution:

Here, we have to find nothing but the unit price or the price of 1 cookie.

This can simply be done by dividing the total cost of cookies with the total number of cookies.

Total cost of 15[tex]x[/tex] cookies is given as $9[tex]x[/tex]

Using unitary method:

Let us divide both the sides with 15[tex]x[/tex], we get:

Total cost of [tex]\frac{15x}{15x}[/tex] cookies is given as [tex]\frac{\$9x}{15x}[/tex]

Total cost of 1 cookie is given as $0.60
