Does 2/3x+3/4=8 and 8x=87 have the same solution ?

Answers

(2/3)x + (3/4) = 8
-(3/4) -(3/4)

(2/3)x = 7.25(3/2)
(3/2)

x = 10.875

8x = 87 Divide both sides by 8

x = 10.875

So yes both sides have the same solution

Hope this helps :)

How are the graphs of the functions y=2(2)^x and y=2(1.1)^x similar?

Answers

if the are equal then they can be similar, otherwise they are not.

Y=2(2)^x ----> y=(4)^x

Y=2(1•1)^x--> y=(2•2)^x----> y=(4)^x

Identify which property of equality is used to transform Equation 1 to Equation 2.Equation 1: x – 6 = 14
Equation 2: x = 20

A.
multiplication property of equality

B.
division property of equality

C.
subtraction property of equality

D.
addition property of equality

Answers

D. addition property of equality

That will be your 100% sure answer!

Answer:

$\boxed{D.}$

Step-by-step explanation:

On A.- Multiplication property of equality is multiplying both sides of an equation by the same number it does not change the equation.

______________________________________________________

On B. - Division property of equality is dividing both sides of an equation by the same non-zero number it does not change the equation.

________________________________________________________

On C.- Subtraction property of equality is subtracting the same number from both sides of an equation it does not change the equation.

________________________________________________________

On D.- Addition property of equality is adding the same number to both sides of an equation it does not change the equation.

x-6=14

First you had to add by six from both sides of an equation form.

x-6+6=14+6

Then simplify by equation.

x=20

Final answer: $\boxed{x=20}$

What's the formula to perimeter

Answers

The formula is:

Perimeter = (the distance all the way around the outside of the figure) .

How to calculate the distance all the way around the outside of the figure
is different for every shape.

A few of them are:

Square . . . . . 4 x the length of one side

Rectangle . . . . . (2) x (length + width)

Circle . . . . . (2 pi) x (radius)

etc.

$The\ perimeter\ of\ any\ polygon\ is\ the\ sum\ of\ the\ lengths \nof\ all\ its\ sides\ (a,\ b,\ c,\ d,\ ...)\n\ntriangle:\ \ \ P=a+b+c\n\nequilateral\ triangle:\ \ \ P=3a \n\nrectangle:\ \ \ P=2a+2b \n\nsquare:\ \ \ P=4 a\n\ndiamond :\ \ \ P=4a\n\ntrapez:\ \ \ P=a+b+c+d\n\nisosceles trapezoid:\ \ \ P=a+b+2c\ \ \ \ \ (c-arm length)\n\nany\ polygon:\ \ \ P=a+b+c+d+...\n----------------\nThe\ perimeter\ of\ a\ circle:\ \ \ P=2 \pi r\ \ \ \ \ (r-radius\ or\ a\ circle)$
