$27.93

You want to know how much she payed for 1 can. So you divide $12 by 9 cans. For one can, she paid $1.33. Now multiply that by 21 cans.
1.33•21=27.93

What’s the answer to this question if your right I’ll keep giving you points

\huge\text{$m\angle O=\boxed{11^{\circ}}$}

Since we know that all angles in a triangle add up to 180^{\circ}, we can solve for x and substitute it back into (x-5)^{\circ} to find m\angle O.

\begin{aligned}m\angle N+m\angle O+m\angle P&=180\\(5x-8)+(x-5)+(6x+1)&=180\end{aligned}

Remove the parentheses and combine like terms.

\begin{aligned}5x-8+x-5+6x+1&=180\\(5x+x+6x)+(-8-5+1)&=180\\12x-12&=180\end{aligned}

Add 12 to both sides of the equation.

\begin{aligned}12x-12&=180\\12x&=192\end{aligned}

Divide both sides of the equation by 12.

\begin{aligned}x=16\end{aligned}

Now that we have the value of x, we can substitute it back into (x-5)^{\circ} to find m\angle O.

\begin{aligned}m\angle O&=(x-5)\\&=16-5\\&=\boxed{11}\end{aligned}

7+11v=9v-9 how do you solve by steps
avanturin [10]
You're solving this equation for the variable 'v', so the main goal is to isolate it on one side of the equation.

     7 + 11v = 9v - 9            Subtract 7 from both sides
7 - 7 + 11v = 9v - 9 - 7       Simplify
           11v = 9v - 16           Subtract 9v from both sides
    11v - 9v = 9v - 9v - 16   Simplify
            2v = -16                 Divide both sides by 2
            \frac{2v}{2} = -\frac{16}{2}                 Simplify
            v = -8          

Check your answer by plugging the value (-8) into the original equation.

7 + 11(-8) = 9(-8) - 9   Simplify the mulitiplication steps
7 + (-88) = -72 - 9     Rewrite 7 + (-88) as 7 - 88
    7 - 88 = -72 - 9     Simplify both sides
         -81 = -81

The check worked out, so your answer is v = -8 .
