What is 3/5 plus 2/3

2 answers:

The answer is 14/15 because we need to make the denominators the same before adding the numerators. It's all about finding the lowest common denominator which is 15. :)

You turn 3/5 to 9/15
You turn 2/3 to 10/15
Then u add 9/15+10-15 = 19/15=1 4/15

Can some one help me with this question: Solve 5x-22=20

Annette [7]

Answer: x = 8.4

Work: So, the goal of this equation is to get x by itself, and the first thing we need to do is get 22 out of that current side. To do that, we are going to add 22 on both sides, cancelling it on the side it's currently on. So, the new equation is 5x = 42. Now, we need to divide 5 on both sides, and like I said, I'll cancel on the side it's currently on. So, the answer is x = 8.4

I hope this helps, and Happy Holidays! :)

The center of a hyperbola is located at the origin. One focus is located at (−50, 0) and its associated directrix is represented

leva [86]

The equation of the hyperbola is : $\frac{x^{2}}{48^2} - \frac{y^{2}}{14^2} = 1$

The center of a hyperbola is located at the origin that means at (0, 0) and one of the focus is at (-50, 0)

As both center and the focus are lying on the x-axis, so the hyperbola is a horizontal hyperbola and the standard equation of horizontal hyperbola when center is at origin: $\frac{x^{2}}{a^{2}} - \frac{y^{2}}{b^{2}} = 1$

The distance from center to focus is 'c' and here focus is at (-50,0)

So, c= 50

Now if the distance from center to the directrix line is 'd', then

$d= \frac{a^{2}}{c}$

Here the directrix line is given as : x= 2304/50

Thus, $\frac{a^{2}}{c} = \frac{2304}{50}$

⇒ $\frac{a^{2}}{50} = \frac{2304}{50}$

⇒ a² = 2304

⇒ a = √2304 = 48

For hyperbola, b² = c² - a²

⇒ b² = 50² - 48² (By plugging c=50 and a = 48)

⇒ b² = 2500 - 2304

⇒ b² = 196

⇒ b = √196 = 14

So, the equation of the hyperbola is : $\frac{x^{2}}{48^2} - \frac{y^{2}}{14^2} = 1$

There are four angles surrounding a single point:

Luden [163]

I think i may know what your asking, is it a angle at a point? I don’t know what your asking so that a guess based off what i know from your question.

DO,-2(x, y)(3, 5). The point (x, y) is (1, 3) (-3/2, -5/2) (-6, -10)
