⇒w=(5x−8)
Explanation:
Let width be w
Then w(4x+1)=20x2−27x−8
So
(?x+?)(4x+1)=20x2−27x−8
Note that
5×4=20 and (−8)×(+1)=−8
⇒w(4x+1)
=(5x-8)(4x+1)=20x2+5x−32x−8
⇒w(5x−8)

PLEASE HELP WILL MARK BRANILIEST
goldenfox [79]

Answer:

87% full

Step-by-step explanation:

<u>To find the solution:</u>

  1. Use the equation p·x=y where x = 13,920 and y = 16,000
  2. Since you are trying to find the percent, divide both sides of the equation by 13,920. p · 13,920(÷13,920) = 16,000(÷13,920)
  3. The step above cancels out the 13,920 leaving you with the answer. p=0.87
  4. 0.87 = 87%

13. (07.05 MC) What is the solution to the equation 5x + 2(x - 4) = 5x + x - 10? (1 point) O​
TEA [102]

Answer:

x = -2

Step-by-step explanation:

5x + 2(x - 4) = 5x + x - 10

First, we need to to multiply out the parathesis in the equation:

5x + 2(x - 4) = 5x + x - 10

5x + 2x - 8 = 5x + x - 10

Next, we can combine "like terms" to simplify the equation further:

5x + 2x - 8 = 5x + x - 10

7x - 8 = 6x - 10

Now we can isolate the variable "x" to one side:

7x - 8 = 6x - 10

x - 8 = -10

x = -2

To check our work, we can replace x with -2 in our original equation:

5x + 2(x - 4) = 5x + x - 10

5(-2) + 2 (-2 - 4) = 5(-2) + -2 - 10

-10 + 2 (-6) = -10 -2 - 10

-22 = -22

I hope this helps!

A line through (-4,6) with slope-3/2 and graph
marin [14]

Answer:

y = -\frac{3}{2}x

Step-by-step explanation:

Given

Passes through: (-4,6)

Slope: -3/2

Required

The equation and graph

The equation is calculated as:

y = m(x - x_1) + y_1

Where

m = -\frac{3}{2}

(x_1,y_1) = (-4,6)

So, we have:

y = -\frac{3}{2}(x --4) + 6

y = -\frac{3}{2}(x +4) + 6

Open bracket

y = -\frac{3}{2}x -6 + 6

y = -\frac{3}{2}x

See attachment for graph
