A math teacher.... :L oh and pretty much any job in the world

I don't know what's up with the numbers at the bottom, but I'll do the title equation.

Distribute 2 to the (x+3)

1: (2*x) + (2*3) = 10

2: 2x + 6 = 10

Subtract 6 from both sides.

3: 2x + [6-6] = [10-6]

4: 2x + 0 = 4

5: 2x = 4

To isolate 'x', divide both sides by 2

6: 2x/2 = 4/2

7: x=2

That is your answer.

So for this, set up a proportion.

$${\frac{{\mathtt{144}}}{{\mathtt{1}}}} = {\frac{{\mathtt{x}}}{{\mathtt{0.6}}}}$$

Cross-multiply to get the answer.

$${\mathtt{0.6}}{\mathtt{\,\times\,}}{\mathtt{144}} = {\mathtt{x}}$$

$${\mathtt{144}}{\mathtt{\,\times\,}}{\mathtt{0.6}} = {\mathtt{144}}{\mathtt{\,\times\,}}\left({\frac{{\mathtt{6}}}{{\mathtt{10}}}}\right)$$

Thus, the answer is 86.4

Tangent is the opposite side over the adjacent side.

Tan(B) in a triangle ABC (where side 'c' is the hypotenuse) would be b/a

For instance, in a triangle with side lengths 3-4-5 (coinciding to 'a', 'b', and 'c' respectively) tan(B) would be 4/3, because the side opposite angle 'B' is 4, and the side adjacent to angle 'B' is 3.

The circumfrence can be found with the formual C=pi*d; d being the diameter.

You are given the radius, which is half of the diameter. So multiply 23.4534 by 2.

Your diameter is 46.91

Now multiply your diameter by pi. 

Your circumfrence is approximately 147.36 units

The area can be found with the formula A=pi*r^2

Square the radius you are given, 45.654^2

That is approximately 2,084.29

Now multiply that by pi.

The area of the circle is approximately 6,547.98 units squared.

To solve this, you would could use the substitution or elimination method. I prefer substitution so that's how I'm going to explain it.

First pick one of the equations to isolate one of your variables. I think x-y=10 is the easier of the two.

We are goin to isolate x. To do this, add y to the other side. x=y+10

You now have a way of finding y. You will plug x=y+10 into the equation you have not used in the place of x.

So instead of x-2y=24, you will have y+10-2y=24. You can solve for y.

Combine like terms -y+10=24

Subtract 10. -y=14

You don't want your variable to be negative, so multiply both sides by -1.

y=-14, you now have a way to solve for x.

Plug y=-14 into the equation x=y+10 in the place of y.

So you will have x=-14+10

Combine to get x=-4 

Check!

Plug your y and x values into one of your equations. 

-4 - (-14)=10

-4 + 14 = 10

This is true.

x= -4 and y= -14

You would have to evaluate 7^5 before you would multiply by that number. Usually, I think that the number that will be multiplied is in parenthesis before. (n)7^5

Order of operations:

1.) parenthesis

2.)exponents

3.)multiplication

4.)division

5.)addition

6.)subtraction

The ratio of 3:5 can be written as a fraction, which can be used in a proportion.

3/5 = 25/x   Remeber to keep the order, if men are on top of the first fraction, make sure they are on top                   of the second fraction.

125=3x        Cross multiply.

41.67=x        Divide by 3.

x= 41.67        42 women are on staff.

Honestly, I'm questioning your squaring of the pieces inside of the parenthesis. 

Also, I don't think you can square those numbers inside if they are seperated by an operation. I think you would have to FOIL.

However, I could be wrong.

To solve for the x^2 = 13.9 you need to square root both sides.

After square rooting both side you will be left with x= ____ .

For the solving of with the natural log (ln). To remove the ln from the equation you will use the e which removes the Ln from the Left side and leaves (2x-1)^2 and e^4. Now you just need to square everything inside of the parenthesis. Which creates 4x -2 = e^4. After removing the -2 by adding +2 to both sides. Now you are left with 2x = e^4. After plugging in the e^4 you take that answer and divide it by 2 which will leave you with the answer of x=______.

the answer is infinity

it isn't a perfect square root whereas if it was for ex 25 then the square root would be 5

√1296 = 36

take 3 and distribute so 3*4p equals 12p and 3*10 equal 30 so it would be 12p+30

i know you are but what am i?

Adding 3 hrs. to 3:45 gives us 6:45.

And 15 more minutes gives us 7:00.

So, we need to add 20 more minutes to this to get a whole 35.

And this gives us 7:20.

The radius = √(29)

So......

Circumference = 2*pi*r  =   2 * 3.14 * √(29)   ≈ 33.8
