How do I subtract fractions

To perform the correct operation as to subtract numbers, make sure the denominators are the same, and then one can then subtract and remove a smaller number from the larger one.

This same method also holds true for adding fractions together as well.

Another way to subtract fractions is to convert them from fraction form to decimal form and then align the decimal points and subtract the values.

Type the slope-intercept equation

natulia [17]

Answer:

y= -2x +1

Step-by-step explanation:

slope- intercept form:

y= mx +c, where m us the gradient and c is the y-intercept.

Let's find the value of m first using the gradient formula.

Gradient= $\frac{y1 - y2}{x1 - x2}$

$m = \frac{ - 3 - 3}{2 - ( - 1)} \\ m = \frac{ - 6}{2 + 1} \\ m = \frac{ - 6}{3} \\ m = - 2$

y= -2x +c

To find the value of c, substitute a pair of coordinates.

When x= -1, y=3,

3= -2(-1) +c

3= 2 +c

c= 3 -2

c= 1

Thus the equation of the line is y= -2x +1.

What is the solution to the equation 13×3/4+x=7(1/4)

yan [13]

I'm going to assume you mean:

13 * (3/4) + x = 7 * (1/4)

Let's go ahead and simplify the right side.

7 * (1/4) = 1.75

So now we have:

13 * (3/4) + x = 1.75

Now let's take care of the right side. Multiplication before addition.

13 * (3/4) = 9.75

9.75 + x = 1.75

To isolate x, we subtract 9.75 from both sides.

9.75 - 9.75 + x = 1.75 - 9.75

x = -8

Hopefully I spaced this well. \('-')/

What is the value of h?

algol [13]

The two angles shown are supplementary angles, meaning that there sum equals 180. Knowing this you can set up an equation and solve for h...

3h + 18 + 15h = 180

Combine like terms

18h + 18 = 180

Subtract 18 to both sides

18h + (18 -18) = 180 - 18

18h = 162

Isolate h by dividing 18 to both sides

18h/18 = 162 /18

h = 9

Hope this helped!
