-4 - -6 = x

There are so many subtraction symbols that this problem can look confusing but you can get rid of two of them. When you subtract from a negative you are really just adding. (Think of debt as a negative number, if you subtract debt that really means you are getting richer so you are actually adding)

So the problem can also be written as:

-4 + 6 = x

Now you can add the two numbers together to get

x = 2

-4-(-6)= 2

negative and negative cancel out to make a positive

so it would be -4+6=2. Also, you can rearrange the equation to 6-4=2, you keep the sign with the number.

Is it possible to this in the ladder method

The LCM is the smallest number that is divisible by 8, 12, and 16.

To find it, I would suggest listing a few multiples of the highest number and seeing if 8 and 12 go into those multiples.

A few multiples of 16 would be: 16, 32, 48, 64

Now we can check if 8 or 12 go into any of those.

8 goes into 16, 32, 48, and 64 but 12 only goes into 48.

Therefore 48 is the LCM.

This is a TVM formula for either a loan or an annuity of $10,000 that either requires or pays a monthly payment of $106.07 per month for 120 months or 10 years. There is NO DIRECT solution for i in this particular formula. However, computer programs and financial calculators have built into them an iteration and interpolation formulae to arrive at the answer very quickly.

They essentially divide 10,000 / 106.07 =94.277...... So, these built-in formulae "guess" an interest rate that gives an answer slightly above 94.277 and another "guess" that gives an answer that is slighly below 94.277. Then they use interpolation between the three results and rapidly hone in on the actual interest rate that balances the equation.

My own computer has this formula already programmed into it and can very rapidly solve for i once I enter all the known variables into it. Doing that, it immediately comes up with 5% compounded monthly, which is i in this particular problem. And it checks.
 

Since we know the values, there is no need for variables. But if the problem said to make an equation with variables it should have told you what values should be variables. If not just replace the 6 with the variable, z, and the 15 with the variable, w.

Then it should look like 8.5z/w = L

Where z equals the total chapters needed to teach and w equals the weeks needed to teach it.

yy just y rlly it no sense

Plz show how too

i believe google can display up to nE306

The dependent variable is the y value and the independent variable is the x value.

So since the slope is change in y over change in x then the slope equals -3/2

Using point slope form, we can create a function to find the y and x intercepts (although the y intercept is basically given in the problem)

y - y₁ = m(x - x₁)

m = slope

y₁ = the y value the problem provides

x₁ = the x value the problem provides

So the equation for the line is:

y - 5 = -3/2(x - 0)

The y intercept is found when x equals zero. Since the problem gives us a point where x equals zero we know that the y intercept is (0, 5).

To find the x intercept we need to set the y value equal to zero in the equation.

0 - 5 = -3/2(x - 0) ----> -5 = -3/2x

Now we multiply both sides by the reciprocal of -3/2 to isolate x

10/3 = x

Now we know the x intercept is (10/3, 0)

With like variables and stuff.

Thanks For Trying!

This makes no sense at all!

4(t-7)=12-t

4t-28=12-t

5t=40

t=8

THXXXXXXXXXXX UR A LIFE SAVER i now start secondary school so thx

Isolate x on one side by subtracting 3 from both sides to get:

-x = -11

Then divide both sides by negative one to get:

x = 11

7(x+3)-2(x+6)-2 simplified is 5x+7.

Here are the steps:

7(x+3)−2(x+6)−2

Use the distributive property...

7(x+3)−2(x+6)−2=(7)(x)+(7)(3)+(−2)(x)+(−2)(6)+−2=7x+21+−2x+−12+−2

Combine like terms...

7x+21+−2x+−12+−2=(7x+−2x)+(21+−12+−2)

=5x+7

Hope this helped. 

An infinite number of fractions could be added to equal 37/50. I don't think that is what you meant though. Could you please elaborate on what you wanted to know.

It can display up to 199! =3.94328933 x 10^372.

I'll give you two answers, since I'm not really sure what this is asking.

πr² is the formula for the area of a circle. 

Here is an example of how to use the formula:

Say that you round π to 3.14 (that's usually how you round π). Also, say r, or the radius (half of the diameter, and the diameter is a line that passes through the center of a circle) is 4.  

4² really means to multiply 4 by itself, 4. Anything with ² means to multiply it by itself once.  Back to our example, 4*4 is 16.

When you see the π and r together (πr) like that, it means to multiply them together. In our example, 16*3.14 is 50.24. 

And there you have it. That's all you do to use the formula.

Hope this helped.

Remember PEMDAS for the order in which to perform operations.

1. P - First you solve anything in parenthesis

2. E - Then you solve anything with an exponent

3. M/D - Then you multiply or divide (neither comes before the other so just solve left to right)

4. A/S - Then you add or subtract (again neither comes before the other so just solve from left to right)

If we solve everything in parenthesis first we get:

14*3 + 12/3

There is nothing with an exponent so we can skip that. There is a multiply and a divide operation so perform those from left to right.

42 + 4

Then finally add to get:

46

To solve this simply take the reciprocal (reverse of both sides) to get:

24/4 = x/1

The equation can just be simplified to

24/4 = x

since anything over one is just itself. Once you simplify the fraction on the left you end up with:

6 = x

3/25 + 3/50(or 1.5/25) + 2/25 =6.5/25 =.26 x 100 = 26% live in those 3 States.

1 - 26% = 74% live in the rest of the States.

If the Xs in the problem mean multiply, the answer would be 6,000,000,000. 

In order to solve this we need to know what a equals.

Right now you're giving us this equation (where u equals the number you are trying to find)

9/a = u

Since there are two unknowns in this equation we would either need a system of equations to solve it, or we would need one of these unknowns to be defined.
