How do I write the proper Algebraic Equation for this word problem

What 3 consecutive integers equal 9? Now I know the answer is 2+3+4 but, how would I write it? I would right it like this: Let X equal the second integer3X = 9 3X ÷ 3 = 9 ÷ 3X = 3 Therefore the

Probability, geometric series

On the real line (-inf, inf), point a resides in the interval 0 Answer:0=3 is 3/7th of the sample space, the required probability is 3/7. Is this correct? Why not, since 0=3, and the question ask wh

Another geometric question

I thought I understood this and there was a question earlier and I guessed at the right answer, but I need to know exactly how to do this. Take the geometric sequence: 9, 18, 36, 72,... Write a rule f

Find the center and radius of (x+3)^2 + (y+8)^2 = 169

Find the center and radius of (x+3)^2 + (y+8)^2 = 169 A. (-3, -8); 13 B. (-8, 3); 13 C. (3, 8); 13 D. (-8, -3); 169-A. (-3, -8); 13-Same as when you find solutions to a factorised quadratic. Take the

How much is 10% off a $57 order

I know its not going to be a lot, but I forgot how to do it in my head. I keep getting $5.07 but something tells me thats not right.-you save $5.70 so your total should be $51.30 Unless they have a

In angle ABC, Ab=1 and BC=100, which of the following must be true about the angles

a) The measure of angle A is the greatest b) The measure of angle B is the greatest c) The measure of angle a and b are equal d) The measure of angle c is the greatest e) The measure of angle c is the

Find the sum of the geometric series...

First term is 4, common ratio is 3, 16 total terms. What is the sum? Thanks!-S_n = a_1[(1-r^n)/(1-r)] S_16 = 4[(1-3^16)/(1-3)] S_16 = 86,093,440 :)

Find the area of a triangle with side lengths 11, 16, and 17 inches

area=√[s(s-a)(s-b)9s-c)]s=(1/2)(a+b+c)a=11b=16c=17s=22 area=√[22(22-11)(22-16)(22-17)]=√[22(11)(6)(5)]=85.206 in²-Is this a right triangle or what?More info would help.

Write an inverse variation equation

The problem reads: The variables x and y vary inversely, and y=7 when x=4. Write an equation that relates x and y, and then find y when x=-2. Thanks for your help!-First write the general equation for

How to find the side of a right triangle if given two side's measures

How do I find the measure of a side of a right triangle if I am provided with two sides? One leg measures 20 units and the hypotenuse measures 25 units, and it is a right triangle. Answer please? Als

How do you figure out the antiderivative of (x+1)(2x-1)

Just FOIL and anti-differentiate the result using the Power Rule to yield: ∫ (x + 1)(2x - 1) dx = ∫ (2x^2 - x + 2x - 1) dx = ∫ (2x^2 + x - 1) dx = 2 ∫ x^2 dx + ∫ x dx - ∫ dx = (2/3)x^3 + (1/2)x^2 - x

Integrate 1/(sin x.cos^3 x)

please help me solve this trouble!!!!!!!-∫ 1 / (sinx cos^3 x) dx = ∫ (cos^2 x + sin^2 x) dx / (sinx cos^3 x) = ∫ dx / (sinx cosx) + ∫ sinx dx / cos^3 x = 2 ∫ cosec (2x) dx + ∫ sinx dx / cos^3 x = 2 *

Why??? Simple math equation doeSN't w0Rk!!!

I want make 6 equal columns on a sheet of paper. The paper is 18.2cm high. I divide 18.2cm by 6 and get 3.30cm............but when I mark the lines out the last column is only 1.8cm !!!!!!! Why oh why

How do you find the parameterization of this curve
