So in order to subtract you need a common denominator. So you multiply 3/4 by 7 and 1/7 by 4 and get 7/28 - 21/28 then you subtract and get - 14/28 or -1/2 if you want to simplify it.

A store prices tapes by raising the wholesale price 50% and adding 25 cents .What must a tape's wholesale price be if the tape s

Andre45 [30]

Let's call the store value as s and the wholesale price as w. A store prices tapes by raising the wholesale price 50%(0.5 in decimals) and adding 25 cents, writing this as an equation, we have

$s(w)=w+0.5w+0.25$

If we invert the equation we're going to find the the wholesale price as a function of the store price.

$\begin{gathered} s=w+0.5w+0.25 \\ s=1.5w+0.25 \\ s-0.25=1.5w \\ w(s)=\frac{s-0.25}{1.5} \end{gathered}$

Now, to find the wholesale price if the sales price is $1.99, we just need to evaluate s = 1.99 on the function we created.

$w(1.99)=\frac{1.99-0.25}{1.5}=1.16$

The wholesale price is $1.16.

What is the quotient (2x2 + 10x + 12) ÷ (x + 3)?

tamaranim1 [39]

We have 2( x^2 + 5x + 6) ÷ (x + 3) = 2(x^2 + 3x + 2x + 6) ÷ (x + 3) = 2[ x( x + 3) + 2( x + 3)] = 2( x+ 3 )( x + 2 ) ÷ ( x + 3 ) = 2( x + 2 ) = 2x + 4.
