What is the answer for x - 4 3?
okay if x-4=3 then x=7 bcause 4+3=x = 4+3=7 and 7-4=3!
X - 3 divided by 12 - 4x?
(x - 3)/(12 - 4x) = (x - 3)/[4(3 - x)] = (x - 3)/[-4(x - 3)] = 1/-4 = -(1/4)
Write three ways to find 3 x 2 x 4?
3 x 2 x 4 = 24 (3 x 2) x 4 = 6 x 4 = 24 3 x (2 x 4) = 3 x 8 = 24 2 x (3 x 4) = 2 x 12 = 24
What is the algebraic expression for four times the sum of a number and 3?
x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
How do you write 4 less than a third of a number?
You would write it as x/3 -4, where x is whatever the number is.
What is Xsquared -4 divided by X plus 3?
-1
What would x be if 3(x 5) is equal to 4(x-2)?
If you mean: 3(x+5) = 4(x-2) then the value of x works out as 23
Divide x2-x-12 by x-4?
A simple way to do this problem would be to factor x^2-x-12 into (x+3)(x-4) we can then write: (x+3)(x-4)/(x-4) and then the (x-4) in the top and bottom of the fraction both cancel leaving just x+3 as the solution.
3 plus 4 x plus 5 31?
3 plus 4 x plus 5 31 when simplified would give x = 23/4.
Where would the brackets go in 2 times 3 plus 4 plus 5 equals 26?
2 x 3 + 4 + 5 = 152 x (3 + 4) + 5 = 192 x (3 + 4 + 5) = 24
What would the volume of a sphere be if the radius is 10 inches?
Volume of a sphere = 4/3 x pi x radius3; (4/3) x 3.1416 x (10 inches)3 = (4/3) x 3.1416 x 1,000 cubic inches = 4,188.8 cubic inches
What dose square mean in math?
"Square" means to times it itself twice. For example, if I were to square 3, it would be 3 x 3. If I were to square four, it would be 4 x 4. Now, to provide a little more information, "cubed" means to times itself three times. So if I were to cube 3, it would be 3 x 3 x 3. If I were to cube four, it would mean 4 x 4 x 4. These are called exponents. Exponents are numbers above the base. Typing, it would be, take 3, for example, 3^2 if you wanted it to be squared. If it would be cubed, it would be typed as 3^3. The first number is the main number, or the base, and the second number, or exponent, is how many to times the base by. For example, 3^2 would mean 3 x 3. The exponent, in writing, would be in smaller text hovering next to the base, just as if you were to write 3rd.

Find x when X to the power of -5 thirds equals 4 without using a calculator?
x^(-5/3) = 4 1/x^(5/3) = 4 x^(5/3) = 1/4 [x^(5/3)]^(3/5) = (1/4)^(3/5) x = 1/4^(3/5) or, x = 4^(-3/5) Check: x^(-5/3) = 4 [4^(-3/5)]^(-5/3) = 4 ? 4 ^(15/15) = 4 ? 4^1 = 4 ? 4 = 4
What is the sum of x and 3 divided by 4?
0.75
How do you differentiate 20((x 1)-3)?
Please can you clarify the following points (i) should there be a + or - sign between x and 1? (ii) do you mean everything in the bracket to the power of -3? I would rewrite this as 20(x+1)^-3 or 20(x-1)^-3 where the ^ means 'to the power of' If it is one of these last two, then differentiating you would get -3*20*(x+1)^-4 or -3*20*(x-1)^-4 (8 means multiplied by ) or simplifying -60(x+1)^-4 or -60(x-1)^-4
