What is the answer to 3x 5x-2x equals 24 what dose x equal?
3x+5x-2x = 24 6x = 24 x = 4
What is the answer for 2x 1 7?
2x = 17 then x = 8.5 2x+1=7 then x = 3 2x - 1 = 7 then x = 4 which is your problem
The length of a rectangle is 1 more than twice its width and the area of the rectangle is 45 what are the dimensions of the rectangle?
Assign the rectangle a width 'x'. From the data in the problem the height is then '2x+1'. Multiplying the two together gives the area of the rectangle, which we know to be 45. In equation for this is: x(2x+1) = 45 or 2x^2 + x = 45. The roots of this equation can then be found either through the quadratic equation or a calculator solver (I used the solver because I'm lazy) and the answers are x = -5 and x= 4.5. The rectangle has a width of 4.5 and a height of 10.
What is the solution to this equation 2x plus 3(x and ndash 10) 45?
This website isn't equipped to reproduce most mathematical symbols in the questions. I'll see if I can translate. 2x + 3(x - 10) = 45 2x + 3x - 30 = 45 5x - 30 = 45 5x = 75 x = 15 Check it. 2(15) + 3(15 - 10) = 45 30 + 15 = 45 It checks.
What is 2x plus 15 plus 2x equals 180?
First of all add all common factors. In par. (2x) + 15 + (2x) = 180 4x + 15 = 180 Divide 4x and 180 by 4. (4x/4) + 15 = (180/4) x + 15 = 45 Then subtract 15 to 15 and 45. x + (15-15) = (45-15) x = 30 Answer is X = 30.
How can you solve -2x equals -4x plus 24 step by step?
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
What is a factor of x² 2x - 24?
If it is x² + 2x - 24, thenx² + 2x - 24 = (x + 6)(x - 4), since 6(-4) = 24 and 6 + (-4) = 2If it is x² - 2x - 24, thenx² - 2x - 24 = (x - 6)(x + 4), since (-6)(4) = 24 and -6 + 4 = -2If it is x2 = 2x - 24, thenx² = 2x - 24x² - 2x + 24 = 0Using the Quadratic Formula:-b ± √b²-4ac2a=2 ± √(-2)²-4(24)2=2 ± √4-962=2 ± √-922You cannot take the square root of a negative number, therefore x² = 2x - 24 is unfactorable.
The width of a rectangle is 12 cm less than the length The perimeter is 156 cm Find the width and the length?
Let the width be x -12 and length be x 2(x-12)+2(x) = 156 2x-24+2x = 156 2x+2x = 156 +24 4x = 180 x = 45 Therefore: width = 33cm and length = 45cm.
What is x in the problem 2x plus 10x - 4 equals 20?
2x + (10x - 4) = 20 2x + 10x - 4 = 20 12x - 4 = 20 12x = 24 x = 2
What is -2x equals -4x 24?
-2x=-4x*24 x=12
One factor of x2-2x-24 is?
x2-2x-24 when factorised = (x+4)(x-6)
Factor the polynomial expression x2 - 2x - 24?
x2 - 2x - 24 = (x - 6)(x + 4)
What number can be decreased by 6 and the result doubled to get 24?
The number is 18. Let x be the number, The equation is (x-6) * 2 = 24 2(x-6) = 24 2x -12 = 24 2x = 24 + 12 2x = 36 x = 18
45 plus x plus 54 plus x?
45 + x + 54 + x 2x + 99
What is the answer to 3x 5x-2x equals 24 what dose x equal?
3x+5x-2x = 24 6x = 24 x = 4
