Write an equation for the situation.

ella [17]

Let a be the variable for the equation.

now equation for the situation is 1a + 2(a-3) = 91.50
1a + 2a - 6 = 91.50
3a = 97.50

thus, a = 97.5/3 = 32.5$

Now, price of first blouse = 32.5
The price of other two blouse = 32.5-3 = 29.5$

What is the solution of the system? use elimination . -12x-y=6 17x+y=4

anyanavicka [17]

To clarify the systems of equations:

$-12x - y = 6$
$17x + y = 4$

We already have opposite coefficients for y, so combine the two equations together:

$5x = 10$

Divide both sides by 5 to get x by itself:

$x = 2$

Because we now know x, we can plug it into one of the equations.

We will plug this value into the first equation:

$-12(2) - y = 6$

$-24 - y = 6$

Add 24 to both sides.

$-y = 30$

Divide both sides by -1 to get y by itself.

$y = -30$

Using elimination, x = 2 and y = -30.

How many times does 6 go into 22

sergeinik [125]

Hey!

We can use long division to solve this,
Let's write it.
$6\overline{|\smallspace22}\space\space\space\space$
Then, divide $22$ by $6$ to get $3$ .
$\begin{matrix}\space\space\space\space\space\space\emptyspace3\space\space\space\space\space\space\space\space\space\space\space\space\\ 6\overline{|\smallspace22}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$
Multiply the quotient by the divisor...
$\begin{matrix}\space\space\space\space\space\space\emptyspace3\space\space\space\space\space\space\space\space\space\space\space\space\\ 6\overline{|\smallspace22}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace8}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$
Subtract $18$ from $22$ .
$\begin{matrix}\space\space\space\space\space\space\emptyspace3\space\space\space\space\space\space\space\space\space\space\space\space\\ 6\overline{|\smallspace22}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace8}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\space\space\emptyspace4\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}$
As you can see, our answer using long division would be 3 with a remainder of 4.

Thanks!
