\frac{z}{5-7}=2\frac{1}{3}\\\\\
\frac{z}{-2}=\frac{7}{3}\ \ \ |Multiply\ by\ 6\\\\
-3z=7*2\\\\
-3z=14 \ \ \ |Divide\ by\ -3\\\\
z=-\frac{14}{3}=-4\frac{2}{3}\\\\
Solution\ is\ \boxed{z=-4\frac{2}{3}}

Complete the table and show work
Alinara [238K]
So the formula for this is for every inch of width, you multiply by 2 to get the length. 

Here, I made a table for it. 

2×2=4

4×2=8

7×2=14

8×2=16 or 16÷2=8

andrey2020 [161]
500 total magazines...

Amy sold 1/9......1/9(500) = 500/9 = 55.5
Garret sold 0.145.....0.145(500) = 72.5
Robbie sold 12/100.....0.12(500) = 60
Carlita sold 0.095.....0.095(500) = 47.5

Garret sold the most

or u could have done it this way...
Amy sold 1/9.....1/9 = 11.1%
Garret sold 0.145 = 14.5%
Robbie sold 12/100.....12/100 = 12%
Carlita sold 0.095....0.095 = 9.5%

u will still get the same answer...Garret

Can someone help me, I don't need to see how u did it just make sure it is correct.
ladessa [460]
Y = - 4x^2 - 3x + 3 This thing is complex with fractions. I have to work it out.
y = -4(x^2 + 3/4 x) + 3
y = -4(x^2 + 3/4 x + (3/8)^2 ) + 3
y = -4(x + 3/8)^2 +3 + 4*(9/64)
y = -4(x + 3/8)^2 + 3 + 9/16
y = -4(x + 3/8)^2 + 3 9/16 Equation in Vertex form. <<<<< answer
y = -4(x + 0.385) + 3.5625 Equation in Vertex form. <<<< answer 
One is in decimal form. One in fraction form. 

the vertex (-3/8, 3 9/16) or alternately
the vertex (-0.375,3.5625)

You might want the graph to confirm my answer.
