cuanto es 3,072 en fraccion ?
Answer:
-0.04x +17.2
Step-by-step explanation:
For a quadratic of the form
, we complete the square by first adding
to each side.
Here, the coefficient b is equal to 10. We take half of this—5—and square it to get 25. We add this to both sides of the equation.
FYI, this equation can easily be factored, so there's no need to complete the square.
Answer:
x = 2
Step-by-step explanation:
10x + 1 = 2(3x + 5) - 1
- mutlipy the 2 to the 3x and the 5
- you should get 10x + 1 = 6x + 10 - 1
- now you have to add the combine terms
- so it will now be 10x + 1 = 6x + 9
- now you.have to get the x's on one side and the constants (numbers alone) on the other side
- so you can subtract the 6x on both sides
- once you do that you wil get 4x + 1 = 9
- After you get this equation you will have to subtract the one from both sides.
- you will get 4x = 8
- All you have to do it divide 4 on both sides. Your final answer is x = 2.
Answer:
y = 5/3 = 1.667
Step-by-step explanation:
Simplifying
5y + 4 + -2y = 9
Reorder
4 + 5y + -2y = 9
Solving
4 + 3y = 9
Solving for y:
Add -4 to each side of the equation.
4 + -4 + 3y = 9 + -4
Combine like terms.
4 + -4 = 0
0 + 3y = 9 + -4
3y = 9 + -4
Combine like terms.
9 + -4 = 5
3y = 5
Divide each side by 3
y = 1.666666667
