What is the solution to y-12=20

Mathematics

Answer:Simplifying

y + -12 = 20


Reorder the terms:

-12 + y = 20


Solving

-12 + y = 20


Solving for variable 'y'.


Move all terms containing y to the left, all other terms to the right.


Add '12' to each side of the equation.

-12 + 12 + y = 20 + 12


Combine like terms: -12 + 12 = 0

0 + y = 20 + 12

y = 20 + 12


Combine like terms: 20 + 12 = 32

y = 32


Simplifying

y = 32

Hey there!

y-12=20

Add 12 to both sides. (do the inverse of subtraction, which is addition)

y=32

Check answer.

32-12=20 <=== checks out :)

I hope this helps!

Find the perimeter and area. (plz help with the answer)
ikadub [295]

Hello!

PERIMETER:

To find the perimeter of the trapezoid, simply add all sides together.

15 + 5 + 9 + 5 = 34

The perimeter is \boxed{ \bf 34~units.}

____________________________________________________________

AREA:

A = \frac{1}{2} h(b_{1} + b_{2})

A = \frac{1}{2} 4(9 + 15)

A = \frac{1}{2} 4(24)

A = 2(24)

A = 48

The area of the trapezoid is \boxed{ \bf 48~units^2}

Answer:

Interval is given with 97% confidence. Thus there is 3% probability that interval is not true.

Step-by-step explanation:

In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence.

<em>Statistically</em>, this means that the person can be 97% sure (not 100%)  that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval.

Small sample size may also lead wrong estimates.

The volume of a box of four earrings is 216 cm³ what is the length of one edge of the box
Iteru [2.4K]

Answer:

I’m pretty positive you divide 216 by 4, since that’s the amount of sides a box normally has. The answer would be 54 cubic centimeters. Please let me know if I’m correct, hopefully this helped.

Answer:

Step-by-step explanation:

27 ) 2x² - x - 1 = 0

2x² - 2x +  x  - 1 = 0

2x ( x - 1) + (x - 1) = 0

(x - 1)(2x + 1) = 0

x - 1 = 0  ; 2x + 1 = 0

x = 1   ;     2x = -1

                  x = -1/2

x = 1 ; -1/2

Option b

28) Area of a rectangle = 24 cm²

length * width = 24

(3x +2 )(2x -1) = 24

3x(2x -1) + 2(2x - 1) = 24

3x *2x - 3x *1 + 2*2x - 2*1 = 24

6x² -3x + 4x - 2= 24

6x² + x - 2 -24 = 0

6x² + x - 26 = 0

6x² -12x + 13x - 26 = 0

6x(x - 2) + 13(x - 2) = 0

(x -2)(6x +13) = 0

x = 2      {Ignore 6x + 13 as it gives negative value}

length = 3x + 2 = 3*2 + 2 = 6 + 2 = 8 cm

Width  = 2x - 1 = 2*2 - 1 = 4 - 1 = 3 cm

29) Area of square = 900 cm²

Side² = 900

(5x)² = 900

25x² = 900

x² = 900/25

x² = 36

x = √36 = √6*6

x = 6 cm

30) base = b cm

height = b + 2

Area of triangle =  24 cm²

\dfrac{1}{2}base*height = 24\\\\\dfrac{1}{2}*b*(b+2) = 24\\

b(b + 2) = 24*2

b² + 2b = 48

b² + 2b - 48 = 0

b²  - 6b + 8b  - 48 = 0

b(b - 6) + 8(b - 6) = 0

(b - 6) (b + 8) = 0

b - 6 = 0    {Ignore b +8 = 0 as it gives negative value}

b = 6 cm

height = 6+ 2 = 8 cm
