8/10 because equal fractions have to be multiplied by 2

No, it is not.

For fractions to be equivalent, they need to have an equal ratio.

For example, 3/9 and 2/6.
They still have the same ratio of 1/3.
Basically, just try dividing them by their simplified fraction.

Arte-miy333 [17]

Answer:

$7\dfrac14$ yards$

Step-by-step explanation:

Regan needs the following:

$2\dfrac{1}{4}$ yards for a dress

$\dfrac{1}{4}$ yards of contrasting fabric for the band at the bottom$\\4\dfrac{3}{4}$ yards for a coordinating jacket.$

Total Length of fabric needed

$= 2\dfrac{1}{4}+\dfrac{1}{4}+4\dfrac{3}{4}\\=2+4+\dfrac{1}{4}+\dfrac{3}{4}+\dfrac{1}{4}\\=6+1+\dfrac{1}{4}\\=7\dfrac{1}{4}$ yards$

The number of yards of 45-in. fabric needed is $7\dfrac14$ yards.$

Answer:

A. $g'(3)=-\frac{1}{2}$

Step-by-step explanation:

We have been given that f be a differentiable function such that $f(3)=15$ , $f(6)=3$ , $f'(3)= -8$ , and $f'(6)= -2$ . The function g is differentiable and $g(x)= f^{-1} (x)$ for all x.
