\frac{6}{15}= \frac{6\div3}{15\div3}= \frac{2}{5}

\frac{6}{15}=\frac{6\cdot2}{15\cdot2}= \frac{12}{30}

\frac{6}{15}=\frac{6\div100}{15\div100}=  \frac{600}{1500}

To obtain an equivalent fraction, you have to multiply or simplify that fraction.

Solve by elimination <br> 5x-15y=10<br> 3x-5y=-6
Dovator [93]
Multiply bottom equation by -3 to add and eliminate y’s.

So...

5x-15y=10
+-9x+15y=18

You get -4x=28 so x=-7

Plug in to get y
5(-7)-15y=10
-35-15y=10
-15y=45
So y=-3

Check in other equation
3(-7)-5(-3)=
-21+15=-6

So x= -7 and y= -3

What is theoretical probability of rolling a number greater than 4 on a standard number cube
sergeinik [125]
So cube faces were numbered 1, 2, 3, 4, 5 and 6.

There are 6 faces in total and there are two faces greater than 4 (face 5 and 6).

So that would be (desired outcomes) / (total outcomes) = 2 / 6 = 1/3

So theoretical probability of rolling a number greater than 4 is 1/3.

Hope this helps.

then take out 3 on the right side.
-7x^2 (x-3)+3 (x-3)
factors to (3-7x2)(x-3)
