Mrs. Potts can make 5 dozen ravioli in 1 hour. Write and solve a direct variation equation to find many she can make in 2 1/2 ho

erica [24]

A direct variation generally has the equation Y=KX
Because Mrs. Potts makes 5 dozen ravioli in 1 hour, this will be the K value.
(5 dozen/1 hr)
To figure out how many she can make in 2 1/2 hrs. You use 5 dozen/1 hr as the K value and multiply that by 2 1/2 hrs (the X value).
The hrs will cancel out and you will be left with the number of ravioli made in 2 1/2 hrs.

What is the result of subtracting the second equation from the first? \begin{aligned} -7x-y &= 0 \\\\ 7x+8y &= -6 \end{a

Kitty [74]

Answer:

$-14x-9y=6$

Step-by-step explanation:

We are given with two equations

first equation is $-7x-y=0$

second equation is

$7x+8y=-6$

we find the result of subtracting two equation

subtract the second equation from the first, so

first equation - second equation, multiply second equation by -1 and then add it with first equation

$-7x-y=0$

$-7x-8y=+6$

Now add both equations, we get

$-14x-9y=6$
