The way to figure this one out is move the 81 over to the other side so you have the equation 16x^4 = 81. Since 81 is not divisible by 16 you have to think of another way to simplify. 16 is a perfect square, x^4 is a perfect square, and 81 is a perfect square. So take the square root of both sides to begin the simplification. 4x^2 = 9. Divide both sides by 4 to get x^2 = 9/4. 9 and 4 are both perfect squares, so undo the square on the x by taking the square root of both sides: x = +/- 3/2.
Answer:
None
Step-by-step explanation:
Let's attempt to solve the equation, and see what happens:
-2(3x-1) = -6x -1
-6x +2 = -6x - 1 (expanding the brackets).
2 = -1 (cancelling out the -6x term from each side).
So, since 2 = -1 is not true, this means there are no solutions to this equation.
22 is the average of the numbers 20,17,24,18,29, and x is what I guess the qusetion is
count them
6 numbers
(20+17+24+18+29+x)/6=22
(108+x)/6=22
times both sides by6 to clear fraction
108+x=132
minus 108 from both sides
x=24
