3st+2su-4sv factorised

1 answer:

5 0

The first step to factorising this expression, is finding what is common in each term.
The GCF of 3, 2 and -4 is 1 therefore we will not have a coefficient of the outside terms.
Then we have st, su and sv
s is common in all of them therefore we can take out s.

So far we have s( )
Now for each term we must find what we multiply by s to reach it.
3st / s = 3t
2su / s = 2u
-4sv / s = -4v

Now just put these values inside the brackets.

s(3t + 2u - 4v)

Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.

now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,

$\bf y=-\cfrac{2}{3}x+7\implies \boxed{3}\cdot y=\boxed{3}\cdot \left( -\cfrac{2}{3}x+7 \right)\implies 3y=-2x+21
\\\\\\
\stackrel{standard~form}{2x+3y=21}$

Answer: 1/8

Step-by-step explanation:

If you look at the circle, there are 4 R, 1B, 2G, and 1Y which then equals 8. Therefor there is a 1/8 chance of the spinner landing on B.

Hope this helps...

Have a great day.
