What is 1/2 plus 5/16

Mathematics
1 answer:
kompoz [17]3 years ago
3 0
Convert the 1/2 to a number that has a 16 in the denominator
because you can only add or subtract numbers that have the same denominator
so 1/2 = 8/16

the 8 + 5 = 13
so  8/16 + 5/16 = 13/16

therefore your answer is 13/16

You want to find the equation for a line that passes through the point (3,-4) and has a slope of -1/2.
Mashcka [7]

Answer:

y = -\frac{1}{2}x -\frac{5}{2}

Step-by-step explanation:

We are given;

  • A point where the line is passing through as (3, -4)
  • The slope of the line -1/2

We are required to determine the equation of the line;

  • Note that, one way we can get the equation of a straight line is when we are given a point where the line is passing through and its slope.
  • Thus, in this case, we can determine the equation;

Taking another point (x, y)

Then; (x, y) , ( 3, -4) and slope -1/2 can give us the equation;

That is;

\frac{y+4}{x-3}=-\frac{1}{2}

Cross multiplication;

2(y+4) = -1 (x-3)

2y + 8 = -x +3

Combining the like terms;

2y=-x-5\\y = -\frac{1}{2}x-\frac{5}{2}

Thus, the equation of the line is; y = -\frac{1}{2}x -\frac{5}{2}

What is the equation of the line that passes through the point (-5,2) and has a slope of 4/5
dedylja [7]

Answer:

4x - 5y + 30 = 0

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

                      $ (y - y_1) = m (x - x_1) $

where $m$ is the slope of the line and

           $ (x_1, y_1) $ is the point passing through it.

Here $m = \frac{4}{5} $ and $ (x_1 , y_1) = (-5,2) $.

Substituting in the equation we get

$ (y - 2) = \frac{4}{5} (x + 5) $

$ \implies 5y - 10 = 4x + 20 $

$ \implies 4x - 5y + 30 = 0 $

zlopas [31]

Answer:

b = 50%

Step-by-step explanation:

P(Heart or Club)

= P(Heart) + P(Club)

= 13/52 + 13/52

= .25 + .25

= .5 --> 50%
