Answer:

25h = x

Step-by-step explanation:

If x is the variable for how many pages she reads in total, 25 multiplied by h (the number of hours) will give you the total pages read!

If she read 1 hour she’d read 25 pages.
So;
25 x 1(total hours) = 25xh = 25h

3ax-n/5=-4 solve for x
ollegr [7]

The solution for x in the equation 3ax - n/5 = -4 is x = -4/3a + n/15a.

<h3>What is the solution for x in the given equation?</h3>

3ax - n/5 = -4

To solve for x, isolate the term that contains x.

3ax - n/5 = -4

3ax = -4 + n/5

Divide each term by the coefficient of x and simplify

3ax/3a = -4/3a + (n/5)/3a

x = -4/3a + (n/5)/3a

multiply (n/5) by the reciprocal of 3a

x = -4/3a + (n/5) × 1/3a

x = -4/3a + n/15a

Therefore, the solution for x in the equation 3ax - n/5 = -4 is x = -4/3a + n/15a.

3X squared plus 2X equals -4 number of solutions
PIT_PIT [208]

Answer:

The given equation has two solutions i.e  \frac{-1+\sqrt{13} }{3} ,  \frac{-1-\sqrt{13} }{3}

Step-by-step explanation:

The given expression as :

3 x² + 2 x - 4

For the quadratic equation in the form of a x² + b x + c , the value of x

x = \frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}

Or, x =  \frac{-2\pm \sqrt{2^{2}-4\times 3\times (-4)}}{2\times 3}

Or, x = \frac{-2\pm \sqrt{4 + 48}}{6}

or, x = \frac{-2\pm \sqrt{52}}{6}

∴ x = \frac{-1\pm \sqrt{13}}{3}

Or, x = \frac{-1+\sqrt{13} }{3} ,  \frac{-1-\sqrt{13} }{3}

Hence The given equation has two solutions i.e  \frac{-1+\sqrt{13} }{3} ,  \frac{-1-\sqrt{13} }{3}  Answer

Hay there can anybody answer this
Alexus [3.1K]

Answer:

  x = 12

Step-by-step explanation:

The two marked angles where the transversal crosses the parallel lines are alternate interior angles, so are congruent. This fact gives you the relation you need to solve for x.

  4x +12 = 60

  4x = 48 . . . . . . subtract 12

  x = 12 . . . . . divide by 4
