Simplify both sides of the equation

3(x-4)+12(x-9)=4x+13

Distribute

(3)(x)+(3)(-4)+(12)(x)+(12)(-9)=4x+13

3x+-12+12x+-108=4x+13

Combine like terms

15x+-120=4x+13

15x-120=4x+13

Subtract 4 from both sides

15x-120-4x=4x+13-4x

11x-120=13

Add 120 to both sides

11x-120+120=13+120

11x=133

Divide both sides by 11

11x/11=133/11

x=133/11

or x= 12 1/11


I hope that's help !

The length of a rectangle is 6 yards longer than its width. If the perimeter of the rectangle is 32 yd, find its area in square
ddd [48]
Let, width = x
Length = x + 6

Now, perimeter, 2(l+b) = 2(x+6+x)
2(2x+6) = 32
4x + 12 = 32
4x = 20
x = 5 &
x+6 = 5+6 = 11

As rectangle's dimensions are 11*5, it's area would be: 11 * 5 = 55 yards²

So, your final answer is 55 Yd²

Hope this helps!

Elizabeth bought a cheese pizza. It was served on a metal tray with a diameter of 22 centimeters. What is the tray's area?
agasfer [191]
<h3>Answer:</h3>

The Area of the tray ≈380 cm

<h3>Solution:</h3>
  • We are given the diameter of the tray, which is equivalent to 22 cm.
  • We are asked to find the area of the tray.
  • Remember the formula:
  • Area of a circle = πr²
  • Where
  • π -> pi (3.14...)
  • r -> radius
  • Notice that we aren't given the radius. We're given the diameter only.
  • No reason to panic. We can easily find the radius by dividing the diameter by 2.
  • The radius is equal to 11 cm.
  • Now, plug the values into the formula:
  • A=π(11)²
  • A=121π
  • A≈380 cm

Hope it helps.

Helpppp Pleaseeeeee!!!!!
inysia [295]

Hi there,

I’m attaching the same image with more information on the graph.

The 4th mark (the middle dashed line) is marking the mean (70).

The 3rd and the 5th are marking the mean less/plus 1 deviation.

So, 70.5 is the 5th mark.

Taking this into account:

The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%

The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%

Good Luck!
