Answer:

2/2

Step-by-step explanation:

Let the numerator and denominator be x/x

10/12÷x/x=5/6

10x/12x=5/6

x/x=5/6÷10/12

x/x=5/6×12/10

x/x=2/2

Therefore the numbers are 2/2

Answer:

2/2

Step-by-step explanation:

To reduce a fraction, you have to divide it by a fraction with the equivalency of 1, since anything else would change the value of the fraction. In this instance, you know that you have the fraction 10/12, and you need to reduce it to 5/6. To do this, you must divide 10/12 by a fraction that equals 1 to create 5/6. Breaking it down, you can know that 10 divided by 2 is 5 and that 12 divided by 2 is 6. 2/2 is equal to 1, so that is the answer.

Find the equation of a line parallel to the line 2x-y-9=0 and passing through the point of intersection of the lines 5x+y+4=0 an

Cerrena [4.2K]

Answer:

$y=2x-3$

Step-by-step explanation:

1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to $2x-y-9=0$

$5x+y+4=0$

$y= -4-5x$

substituting the value of y in $2x+3y=1$ :

$2x +3(-4-5x)=1\\\\2x-12-15x-1=0\\-13x=13x\\x= \frac{13}{-13}= -1$

substituting x=-1 in y= -4-5x:

$y= 1$ (upon solving, you should get this)

$(x,y)= (-1,1)$

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)

$2x-y-9=0\\2x-9=y\\y= 2x-9$

$y= mx+c\\$

-1= 2 x 1 +c

-3=c

y= 2x-3

How to solve question one ?

denis-greek [22]

-30-5x=-4x-6(5+4x)

First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x

Then, you can add like terms to get -30-5x=-30-28x

Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x

Finally, you divide both sides by -23 to get 0=x
