Step-by-step explanation:

Step 1: Make sure the bottom numbers (the denominators) are the same

Step 2: Add the top numbers (the numerators), put that answer over the denominator

Step 3: Simplify the fraction (if needed)

ex. 2/3 + 2/6

I have multiplty 2/3 *2/2  in other to have matching denominators.

when I finish multiplying 2/3 *2/2 i get 4/6 and now I have a fraction that looks like this 4+2/6. Now I add 4 and 2 and u get 6 and now I have 6/6 and i once u simplify it I get 1.

drek231 [11]

Answer:

0.225

Step-by-step explanation:

Total outcomes of choosing 5 out of 18 members = 18C5

Outcomes of choosing 2 out 11 favourers, 3 out of 7 members  =          11C2 & 7C3

Probability = Favourable outcomes / Total outcomes

= ( 11C2 x 7C3 ) / 18C5

<u>[ { 11 ! / 2! 9! } {7 ! / 3! 4! } ] </u>

       [ 18 ! / 5! 13! ]

( 55 x 35 ) /  8568

1925 / 8568

= 0.2246 ≈ 0.225

I WILL GIVE BRAINLIEST PLEASE HELP!!!
Rudik [331]

Answer:

1/x+2

Step-by-step explanation:

To find the inverse of the function, try switching the x value with the y value or function value

something like: x=1/g(x)-2

then, just manipulate the equation so that g(x) is by itself again, but this time, since it is an inverse, it's denoted as g-1(x)

x=1/g-1(x)-2

x+2=1/g-1(x)

(g-1(x))(x+2)=1

g-1(x)=1/(x+2)

Justin is asked to solve the following system of linear equations using the elimination method.
romanna [79]

Alright, lets get started.

Justin is asked to solve the linear equations using elimination method.

By using elimination method means we have to multiply some numbers in our given equations in such a way that the co-efficient of x or y become same in both equations so that we could add or subtract them to cancel one of the term either x or y.

So, given equations are :

5x - 12 = 3

-20x + 14 y = 13

See we have 5x in first equation and -20x in second equation.

So, we try to change 5x into 20 x by multiplying it with 4, both of the equations will have 20 x in common

Lets multiply 4 in first equation

4 * (5x-12y) = 4 * 3

20x - 48y = 12

Now both equations could be added and 20 x will be cancelled out and we could easily find the value of y then solve for x.

So, Justin should try to change 5 so that it will be cancels, so option B  :  Answer

Hope it will help :)
