the stick is a 7 by 3

Answer:

Hello,

why not 700 ?

Step-by-step explanation:

$n=\overline{abcd}\\a\in \{3,4,5,6,7,8,9\}: 7\ possibilities\\b\in\{4,8\} :2\ possibilities\ :0 \ in\ USA\ is\ not\ a\ multiple\ of\ 4\\c \in\{0,1,2,3,4,5,6,7,8,9}: 10\ possibilities\\d \in \{0,2,4,6,8\}:5\ possibilities\\$

7*2*10*5=700

Impossible to reach 3000 since 2nd digit is 4 or 8.

Solve for y:5x-8y=40

bearhunter [10]

Solve for y means we need to isolate y from the equation:

We need to use inverse operations to solve equations:

$\begin{gathered} 5x-8y=40 \\ -8y=40-5x \\ y=\frac{-5}{-8}x+\frac{40}{-8} \\ y=\frac{5}{8}x-5 \end{gathered}$
