Which of the following is equivalent to x+1/y divided by g+1/h
Vikki [24]

Answer:

B) x + 1/y times h/g+1

Step-by-step explanation:

We need to divide \frac{x+1}{y} by \frac{g+1}{h} then match with given choices to find the correct equivalent result.

where given choices are:

A) x/y times h/g

B) x + 1/y times h/g+1

C) x+ 1/y divided h/g+1

D) y/x+1 divided g+1/h

So let's divide  \frac{x+1}{y} by \frac{g+1}{h}

\frac{\left(\frac{x+1}{y}\right)}{\left(\frac{g+1}{h}\right)}

we are allowed to flip the bottom fraction and change division sign into multiplication. So we get:

=\left(\frac{x+1}{y}\right)\cdot\left(\frac{h}{g+1}\right)

Hence correct choice is: B) x + 1/y times h/g+1

Use a number line to show the sum of 6 + (–7).
mylen [45]
So there is a rule
(+)(+)=+
(-)(+)= -
(+)(-)= -
So now if you subtract 6 with 7 you will end up having -1 as you’re answer. Hope this helps

bekas [8.4K]

Answer:

\dfrac{-2}{3} \div 2\dfrac{1}{4} = \dfrac{-8}{27}

Step-by-step explanation:

Given

\dfrac{-2}{3} \div 2\dfrac{1}{4} =

Required

Solve

Start by converting the mixed number to improper fraction

\dfrac{-2}{3} \div \dfrac{9}{4} =

Convert the division to muliplication

\dfrac{-2}{3} * \dfrac{4}{9} =

\dfrac{-2*4}{3*9}=

\dfrac{-8}{27}

Hence:

\dfrac{-2}{3} \div 2\dfrac{1}{4} = \dfrac{-8}{27}

Factor by grouping : xy + 6y - 2x - 12 (if you don't know the answer don't comment)
alexira [117]
<h3> Hey There today we will solve your problem</h3>

First we will factor out y from xy+6y which gives us y(x+6)

Next we will factor out -2 from -2x-12 which gives us -2(x+6)

This gives us the equation

y(x+6)-2(x+6)

then factor out the common term  x+6<em> and we get</em>

<em />\left(x+6\right)\left(y-2\right)
