Answer:

x=\frac{(c-a)}{b} is the answer.

Step-by-step explanation:

If a, b and c are constants.

Given equation is a + bx = c

Now to get the value of x we can solve the given equation.

First we subtract a from each side of the equation.

a - a + bx = c - a

bx = (c - a)

Now we divide each side of the equation by b.

\frac{bx}{b}=\frac{(c-a)}{b}

x=\frac{(c-a)}{b}

Therefore, x=\frac{(c-a)}{b} will be the answer.

The answer would be x=(a+c)/b. Hope this helped could I possibly get brainliest?

What’s the length of the leg?
AveGali [126]

Answer:

a = 4 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 3² = 5²

a² + 9 = 25 ( subtract 9 from both sides )

a² = 16 ( take the square root of both sides )

a = \sqrt{16} = 4

Step 1: Use quadratic formula with a=-3, b=-4, c=-4.
x=
−b±√b2−4ac
2a
x=
−(−4)±√(−4)2−4(−3)(−4)
2(−3)
x=

3+-√(-3)^2 - 4(5)(-1)
Alona [7]

Answer:

Step-by-step explanation:

Easy way to do this is step by step.  Your quadratic, from your entry, must be

5x^2-3x-1.

Step by step looks like this, one thing at a time:

x=\frac{3+\sqrt{(-3)^2-4(5)(-1)} }{2(5)} becomes

x=\frac{3+\sqrt{9-(-20)} }{10} becomes

x=\frac{3+\sqrt{9+20} }{10}

and this of course is

x=\frac{3+\sqrt{29} }{10}

Do the same with the subtraction sign to get the other solution.

If you're unsure of how to enter it into your calculator, do it step by step so you don't mess up the sign.  If you enter it incorrectly, you could end up with an imaginary number when it should be real, or a real one that should be imaginary.

Just my advice as a high school math teacher.
