What is G equivalent to in 21.8-G=9.5???

Answers

start with the equation then subtract 21. 8 from both sides. u get -G= -12.3 then divide both sides by -1 and you get G-12.3
g is equal 12.3 in this equation

Plzzzzz help............Twelve decreased by twice a number is the same as 8 times the sum of the number plus 4. What is the number?Is the equation 2x-12=8(x+4)

Answers

Okay, the equation would be 12 - 2x = 8(x + 4), you got close!

what i would do first is distribute to get rid of those evil parenthesis and make  this all simple ^-^

So, we take 8 times x, and 8 times 4.

Our equation, is now 12 - 2x = 8x + 32

Now, what i would do, is simplify it. Get x to one side, and a whole number to the other. Well, for me it would be easier to keep the larger number on the right, and x on the left!

So we have to be fair, and keep it equal! So, i would start with.... subtracting 32. Since its a positive 32, to cancel it out we have to subtract 32, to get to zero! so, by subtracting 32 on both sides ( 12 - 32 and 32 - 32) we end up with -20 - 2x = 8x

Now looking at - 20 - 2x = 8x, i can see what i need to do. i need to get x to one side, and whole numbers to the other. There are no whole numbers on the right, just variables and coefficients, so i have to get that x away from the left!

So, im going to add 2x on both sides, to eliminate it! So we add 2x on the left to cancel it out, and add 2 x on the right to balance it out! We are now left with -20 = 10x

Now what we do is we get rid of that tag along right by the x! Yep, that little 10 there! He has to go!

How to we get rid of him? Well, he is being multiplied by the x! So, we have to do the opposite and divide to get him alone. So, we divide by 10 on both sides, and we are left with -2 = x!

Now, time to check your answer! Basically, you replace x with -2 in the equation! Here we go:

12 - 2(-2) = 8(-2 + 4)

First we should start with multiplying! when we multiply the -2 in the equation, we get 12 + 4 = 8(2), and we can finish that off by simplifying it to 12 + 4 = 16

when we simplify it and add 12 + 4, we get 16. So we are left with 16 = 16.

This equation is true, so we are right! -2 DOES equal x!

If anyone can help me answer this it would be great thx

ok so remember
area=pir^2
area=256pi

256pi=pir^2
divide both sides by pi
256=r^2
squaer root
16=r

find r and d
d=2r
d=2(16)
d=32

radius=16ft
diameter=32ft




RADIUS:A=3.14*r^2
area=256pi

256*3.14=3.14*r^2
divide both sides by 3.14
256=r^2
square root
16=r


DIAMETER:
3.Now double the radius to get the diameter.32 is the diameter.


radius=16ft
diameter=32ft

How to tell whether its a prime or composite number

Answers

Prime numbers have only 2 factors 1 and its number for example:
2, 3, 5, 7, 11, 13, 17, 19, 23

Like this 1*2. Or 3*1

Composite numbers have more than two factors for example :
0, 4, 6, 8, 9, 10, 12, 14 15, 16..

For example 0 has many factors
0 times 3 0times 4

Step-by-step explanation: You know that it is a prime if the only number divisible by the number is one. If there are more numbers than 1 then it is composite.


The bottom of a shopping bag measures 8 inches by 10 inches. th bag has a height of 12 inches. how much paper is needed to make the bag?A:256 in^2
B: 296 in^2
C: 512 in^2
D: 592 in^2

Answers

512 in.^2 you find the area of each side. the bottom is 8*10 the front and back are 2(12*10) and the sides 2(12*8). Do the math and you get 512in ^2
The answer is C. 512in^2 you find the area of each side the bottom is 8*10 then the front and back 2(12*10)and the sides 2(12*18).
