-5x-9+9x=-6x+3

So first combine the two variables on the left side: (-5x plus 9x)
4x - 9 = -6x + 3
then add 6x to both sides. (this moves it from the right side to the left side).
10x - 9 = 3
then, add 9 to both sides.
10x = 12

Now, divide both sides by 10 to get x.

x=1.2

2^-5=1/2^5=

=1/ 2*2*2*2*2

You can either use your calculator or simply multiply 2 five times:)

2^5=32

So it would be 1/32

32 over 50.

Simplify by dividing both sides by their greatest common factor (the biggest number that can divide into both numbers.
In this case it would be 2.
So each number divided by 2 would be:

16/25

If you want to find the percentage, divide with a calculator,
Or, since 25 times 4 is 100, just multiply both numbers by 4
= (16*4) / (25*4)
=64/100

This would be 64 percent:)

if an ant walk 19cm in minute how far does it walk if the perimeter is 3m by 4m.

Do you mean how long it will take for it to walk that perimeter?

First, find the total length of the perimeter:
I'm assuming it is a rectangle/parallelogram.
So there will be two sides with the length of 3m, and two sides with the length of 4m.

The perimeter would be:
P=2(3) + 2(4)
P=6+8
P=14

This is in meters, and one meter equals 100 centimeters.
To find 14 meters in centimeters, multiply it by 100.

That would be 14000 cm.

Now, you can use a ratio to find the time:
19cm/1=14000/x

How can you find the answer to 10 divided by 6 as a decimal?

First, write it as a fraction, 10/6

6 can divide into 10 one time, with a remainder of 4.
So that would be:
1 and 4/6

4/6 simplifies to 2/3, or 0.6666666...

So the answer in decimal form would be:
1.6666.....

3^1-2x=243

Well, anything to the power of 1 is that number itself.
So this would be:
3-2x = 243
subtract 3 from both sides to isolate the variable.
-2x = 240
Now just divide both sides by -2 to find x.

I think interpolation involves using a regression line and uses specific rules to approximate(?)
