It is 80
the 4th root of 80 equals 2.9907
Equation: x^2 +2kx +10x +k^2 +5 = 0 Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0 Multiplying out the brackets: 4k^2 +40K +100 -4k^2 -20 = 0 Collecting like terms: 40k +80 = 0 => 40k = -80 => k = -80/40 Therefore the value of k = -2
84
80=4x, z=6x. find Z. x=80/4, x=20. z=6x20 z=120 answer= 120
Oh, what a happy little equation we have here! Let's bring some joy to this math problem. To find the value of x, we need to isolate it by moving the numbers around. Start by subtracting 1 from both sides, then divide by -10. And just like that, you've found the value of x - it's -8.
8 = 10x/(10 + x) Multiply both sides by (10 + x) to give: 8*(10+x) = 10x Simplify: 80 + 8x = 10x Subtract 8x from both sides: 80 = 2x Divide both sides by 2: 40 = x
Subtracting gives: 10x = 80 so x = 8 and y = 5
4x +13 = 93-6x. Adding 6x to each side gives: 10x+13 = 93. Subtracting 13 from each side gives: 10x = 80. Dividing both sides by 10 gives: x = 8.
3 times 80/3 = 80
actually,10x squared minus 17 equals 63 would come out to x equals the square root of 8.to work this out, you would first at 17 to both sides to get 10x squared alone.63 plus 17 equals 80. you now have 10x squared equals 80. then divide each side by ten to get x squared alone. 80 divided by 10 equals 8. now you have x squared equals eight. finally, to find x, you find the square root of each side. x squared's square root is x, and 8's square root is 2.82842712 but I'm assuming you only have to write out x=√8.but the other answer was a good try:)Improved Answer:-10x2-17x = 6310x2-17x-63 = 0When factored: (5x+9)(2x-7) = 0Therefore the roots of the quadratic equation are: x = -9/5 and x = 7/2
120% of 80 equals 96. 96/80 = 1.2 = 120%
Isolate the variable. Get it by itself. 9+11x=89+x 9+11x-1x=89+x-1x Subtraction property of equality 9+10x=89 9+10x-9=89-9 subtraction property of equality 10x=80 x=8 division property of equality.
Subtract 2x from each side: 30 = 10x - 50;Add 50 to each side: 80 = 10xDivide each side by 10: 8 = x
80 is the product
2.9906975624424411 to the power of 4 equals 80.
