Thanks Chris :)

You'll most likely have better chances of getting help with proofs in these forums https://www.physicsforums.com/forums/general-math.73/

Thanks 

It says Jill gave away 2 apples and since it says Jill HAS 3 apples...if she picks 2 more she has 5. 

Unless c = 1 [ and all the other terms are non-zero] you cannot literally add these.......[if any of the other terms are 0, the sum = 0 ]

We can factor this sum as  ...   ab (c + 1)

3/10 < 9/20< 3/5 < 17/25

Already answered here:   http://web2.0calc.com/questions/write-the-following-fractions-in-order-from-smallest-to-largest-3-10-9-20-17-25-3-5

40/54 = 20/27

1427/1824  x 100 = 78.23%

First, Im going to explain how powers work. So say the question is 3 to the fifth power, you multiply the number by itself the amount of times equal to the value, in this case five. So it would look like 3x3x3x3x3=243, so to answer your question 25, because 5x5=25. 

5^2 = 5 x 5 = 25

yx-a=cx    add a to both sides

yx  = cx + a     subtract  cx from both sides

yx - cx = a    factor out x on the left

x( y - c)  = a    divide both sides by (y - c)

x =  a /(y -c)

Thank you so much! :)

add -cx   and a to both sides of equation

yx - cx =a

x (y-c) = a

x = a/(y-c)

Here it is step by step:

Solve for x:
x y-a = c x
Isolate x to the left hand side.
Subtract c x-a from both sides:
x (y-c) = a
Solve for x.
Divide both sides by y-c:
Answer: | 
| x = a/(y-c)

My mistake (#2)   agree with #3     98.56 x 10^-18     or 9.856 x 10^-17 is the correct answer

Nice pics of that Cornwall area, Melody....!!!!

could you show the work, I am confused

yx-a=cx

I need x in the terms of the others, thanks.

x = -a/(c-y)

what is Loge0.077

If this means: Log (e^.077), then Ln=.077=Log(base 10)=.03344

Write each number using the same denominator; one common denominator = 100.

3/10    =  30/100

9/20    =  45/100

17/25  =  68/100

3/5     =  60/100

Now, compare numerators:  30/10  <  45/100  <  60/100  <  68/100

So, 3/10  <  9/20  <  3/5  <  17/25

What is 9-j=10

-j=10-9 we move all numbers to one side and change the sign from + to -

-j=1 we multiply both sides by -1

j=-1 which your answer, because: 9 - (-1)=10=9 + 1=10

Problem:  9 - j  =  10.

Procedure:  get the variable alone on one side.

First:  remove 9 from the left side by subtracting 9 from both sides:  (9 - j) - 9  =  10 - 9

Simplify:  - j  =  1

To solve for j, we need to eliminate the - sign from the left side; multiply both sides by -1:

     -1( -j )  =  -1(1)

Simplify:  j  =  -1
